7f3fdd40a7 Power management updates for v4.16-rc1
- Define a PM driver flag allowing drivers to request that their
    devices be left in suspend after system-wide transitions to the
    working state if possible and add support for it to the PCI bus
    type and the ACPI PM domain (Rafael Wysocki).
 
  - Make the PM core carry out optimizations for devices with driver
    PM flags set in some cases and make a few drivers set those flags
    (Rafael Wysocki).
 
  - Fix and clean up wrapper routines allowing runtime PM device
    callbacks to be re-used for system-wide PM, change the generic
    power domains (genpd) framework to stop using those routines
    incorrectly and fix up a driver depending on that behavior of
    genpd (Rafael Wysocki, Ulf Hansson, Geert Uytterhoeven).
 
  - Fix and clean up the PM core's device wakeup framework and
    re-factor system-wide PM core code related to device wakeup
    (Rafael Wysocki, Ulf Hansson, Brian Norris).
 
  - Make more x86-based systems use the Low Power Sleep S0 _DSM
    interface by default (to fix power button wakeup from
    suspend-to-idle on Surface Pro3) and add a kernel command line
    switch to tell it to ignore the system sleep blacklist in the
    ACPI core (Rafael Wysocki).
 
  - Fix a race condition related to cpufreq governor module removal
    and clean up the governor management code in the cpufreq core
    (Rafael Wysocki).
 
  - Drop the unused generic code related to the handling of the static
    power energy usage model in the CPU cooling thermal driver along
    with the corresponding documentation (Viresh Kumar).
 
  - Add mt2712 support to the Mediatek cpufreq driver (Andrew-sh Cheng).
 
  - Add a new operating point to the imx6ul and imx6q cpufreq drivers
    and switch the latter to using clk_bulk_get() (Anson Huang, Dong
    Aisheng).
 
  - Add support for multiple regulators to the TI cpufreq driver along
    with a new DT binding related to that and clean up that driver
    somewhat (Dave Gerlach).
 
  - Fix a powernv cpufreq driver regression leading to incorrect CPU
    frequency reporting, fix that driver to deal with non-continguous
    P-states correctly and clean it up (Gautham Shenoy, Shilpasri Bhat).
 
  - Add support for frequency scaling on Armada 37xx SoCs through the
    generic DT cpufreq driver (Gregory CLEMENT).
 
  - Fix error code paths in the mvebu cpufreq driver (Gregory CLEMENT).
 
  - Fix a transition delay setting regression in the longhaul cpufreq
    driver (Viresh Kumar).
 
  - Add Skylake X (server) support to the intel_pstate cpufreq driver
    and clean up that driver somewhat (Srinivas Pandruvada).
 
  - Clean up the cpufreq statistics collection code (Viresh Kumar).
 
  - Drop cluster terminology and dependency on physical_package_id
    from the PSCI driver and drop dependency on arm_big_little from
    the SCPI cpufreq driver (Sudeep Holla).
 
  - Add support for system-wide suspend and resume to the RAPL power
    capping driver and drop a redundant semicolon from it (Zhen Han,
    Luis de Bethencourt).
 
  - Make SPI domain validation (in the SCSI SPI transport driver) and
    system-wide suspend mutually exclusive as they rely on the same
    underlying mechanism and cannot be carried out at the same time
    (Bart Van Assche).
 
  - Fix the computation of the amount of memory to preallocate in the
    hibernation core and clean up one function in there (Rainer Fiebig,
    Kyungsik Lee).
 
  - Prepare the Operating Performance Points (OPP) framework for being
    used with power domains and clean up one function in it (Viresh
    Kumar, Wei Yongjun).
 
  - Clean up the generic sysfs interface for device PM (Andy Shevchenko).
 
  - Fix several minor issues in power management frameworks and clean
    them up a bit (Arvind Yadav, Bjorn Andersson, Geert Uytterhoeven,
    Gustavo Silva, Julia Lawall, Luis de Bethencourt, Paul Gortmaker,
    Sergey Senozhatsky, gaurav jindal).
 
  - Make it easier to disable PM via Kconfig (Mark Brown).
 
  - Clean up the cpupower and intel_pstate_tracer utilities (Doug
    Smythies, Laura Abbott).

Pull power management updates from Rafael Wysocki:
 "This includes some infrastructure changes in the PM core, mostly
  related to integration between runtime PM and system-wide suspend and
  hibernation, plus some driver changes depending on them and fixes for
  issues in that area which have become quite apparent recently.

  Also included are changes making more x86-based systems use the Low
  Power Sleep S0 _DSM interface by default, which turned out to be
  necessary to handle power button wakeups from suspend-to-idle on
  Surface Pro3.

  On the cpufreq front we have fixes and cleanups in the core, some new
  hardware support, driver updates and the removal of some unused code
  from the CPU cooling thermal driver.

  Apart from this, the Operating Performance Points (OPP) framework is
  prepared to be used with power domains in the future and there is a
  usual bunch of assorted fixes and cleanups.

  Specifics:

   - Define a PM driver flag allowing drivers to request that their
     devices be left in suspend after system-wide transitions to the
     working state if possible and add support for it to the PCI bus
     type and the ACPI PM domain (Rafael Wysocki).

   - Make the PM core carry out optimizations for devices with driver PM
     flags set in some cases and make a few drivers set those flags
     (Rafael Wysocki).

   - Fix and clean up wrapper routines allowing runtime PM device
     callbacks to be re-used for system-wide PM, change the generic
     power domains (genpd) framework to stop using those routines
     incorrectly and fix up a driver depending on that behavior of genpd
     (Rafael Wysocki, Ulf Hansson, Geert Uytterhoeven).

   - Fix and clean up the PM core's device wakeup framework and
     re-factor system-wide PM core code related to device wakeup
     (Rafael Wysocki, Ulf Hansson, Brian Norris).

   - Make more x86-based systems use the Low Power Sleep S0 _DSM
     interface by default (to fix power button wakeup from
     suspend-to-idle on Surface Pro3) and add a kernel command line
     switch to tell it to ignore the system sleep blacklist in the ACPI
     core (Rafael Wysocki).

   - Fix a race condition related to cpufreq governor module removal and
     clean up the governor management code in the cpufreq core (Rafael
     Wysocki).

   - Drop the unused generic code related to the handling of the static
     power energy usage model in the CPU cooling thermal driver along
     with the corresponding documentation (Viresh Kumar).

   - Add mt2712 support to the Mediatek cpufreq driver (Andrew-sh
     Cheng).

   - Add a new operating point to the imx6ul and imx6q cpufreq drivers
     and switch the latter to using clk_bulk_get() (Anson Huang, Dong
     Aisheng).

   - Add support for multiple regulators to the TI cpufreq driver along
     with a new DT binding related to that and clean up that driver
     somewhat (Dave Gerlach).

   - Fix a powernv cpufreq driver regression leading to incorrect CPU
     frequency reporting, fix that driver to deal with non-continguous
     P-states correctly and clean it up (Gautham Shenoy, Shilpasri
     Bhat).

   - Add support for frequency scaling on Armada 37xx SoCs through the
     generic DT cpufreq driver (Gregory CLEMENT).

   - Fix error code paths in the mvebu cpufreq driver (Gregory CLEMENT).

   - Fix a transition delay setting regression in the longhaul cpufreq
     driver (Viresh Kumar).

   - Add Skylake X (server) support to the intel_pstate cpufreq driver
     and clean up that driver somewhat (Srinivas Pandruvada).

   - Clean up the cpufreq statistics collection code (Viresh Kumar).

   - Drop cluster terminology and dependency on physical_package_id from
     the PSCI driver and drop dependency on arm_big_little from the SCPI
     cpufreq driver (Sudeep Holla).

   - Add support for system-wide suspend and resume to the RAPL power
     capping driver and drop a redundant semicolon from it (Zhen Han,
     Luis de Bethencourt).

   - Make SPI domain validation (in the SCSI SPI transport driver) and
     system-wide suspend mutually exclusive as they rely on the same
     underlying mechanism and cannot be carried out at the same time
     (Bart Van Assche).

   - Fix the computation of the amount of memory to preallocate in the
     hibernation core and clean up one function in there (Rainer Fiebig,
     Kyungsik Lee).

   - Prepare the Operating Performance Points (OPP) framework for being
     used with power domains and clean up one function in it (Viresh
     Kumar, Wei Yongjun).

   - Clean up the generic sysfs interface for device PM (Andy
     Shevchenko).

   - Fix several minor issues in power management frameworks and clean
     them up a bit (Arvind Yadav, Bjorn Andersson, Geert Uytterhoeven,
     Gustavo Silva, Julia Lawall, Luis de Bethencourt, Paul Gortmaker,
     Sergey Senozhatsky, gaurav jindal).

   - Make it easier to disable PM via Kconfig (Mark Brown).

   - Clean up the cpupower and intel_pstate_tracer utilities (Doug
     Smythies, Laura Abbott)"

Alexei Starovoitov says:

====================
pull-request: bpf-next 2018-01-26

The following pull-request contains BPF updates for your *net-next* tree.

The main changes are:

1) A number of extensions to tcp-bpf, from Lawrence.
    - direct R or R/W access to many tcp_sock fields via bpf_sock_ops
    - passing up to 3 arguments to bpf_sock_ops functions
    - tcp_sock field bpf_sock_ops_cb_flags for controlling callbacks
    - optionally calling bpf_sock_ops program when RTO fires
    - optionally calling bpf_sock_ops program when packet is retransmitted
    - optionally calling bpf_sock_ops program when TCP state changes
    - access to tclass and sk_txhash
    - new selftest

2) div/mod exception handling, from Daniel.
    One of the ugly leftovers from the early eBPF days is that div/mod
    operations based on registers have a hard-coded src_reg == 0 test
    in the interpreter as well as in JIT code generators that would
    return from the BPF program with exit code 0. This was basically
    adopted from cBPF interpreter for historical reasons.
    There are multiple reasons why this is very suboptimal and prone
    to bugs. To name one: the return code mapping for such abnormal
    program exit of 0 does not always match with a suitable program
    type's exit code mapping. For example, '0' in tc means action 'ok'
    where the packet gets passed further up the stack, which is just
    undesirable for such cases (e.g. when implementing policy) and
    also does not match with other program types.
    After considering _four_ different ways to address the problem,
    we adapt the same behavior as on some major archs like ARMv8:
    X div 0 results in 0, and X mod 0 results in X. aarch64 and
    aarch32 ISA do not generate any traps or otherwise aborts
    of program execution for unsigned divides.
    Given the options, it seems the most suitable from
    all of them, also since major archs have similar schemes in
    place. Given this is all in the realm of undefined behavior,
    we still have the option to adapt if deemed necessary.

3) sockmap sample refactoring, from John.

4) lpm map get_next_key fixes, from Yonghong.

5) test cleanups, from Alexei and Prashant.

1d65b1c886 powerpc/cell: Remove axonram driver
The QS21/22 IBM Cell blades had a southbridge chip called Axon. This
could have DDR DIMMs attached to it, though they were not directly
usable as RAM, instead they could be used as some sort of buffer, if
applications were written specifically to use the block device
provided by the driver.

Although the driver supposedly had direct access support, it was
apparently never tested (see commit 91117a2024 ("axonram: Fix bug in
direct_access")).

These machines have not been available for over 5 years, and were
never widely in use. It seems highly unlikely anyone is using this
driver.

In general we're happy to leave old drivers in the tree, but because
DAX is involved this driver is caught up in the ongoing work in that
area, but none of the DAX folks are able to test it.

So remove the driver, if any one *is* using it, we'll be happy to put
it back.

regulator: added support for suspend states
Some systems need to set regulators to specific states when they enter
low power modes, especially around CPUs. There are many of these modes
depending on the particular runtime state.

Currently the regulator consumers are not granted permission to change
suspend state of regulator devices, the constraints are configured at
startup.  In order to allow changes in a vlotage range, we need to add
new properties for voltage range and a flag to give permission to
change the suspend voltage and suspend on/off in suspend mode.

f168f1098d ovl: add support for "nfs_export" configuration
Introduce the "nfs_export" config, module and mount options.

The NFS export feature depends on the "index" feature and enables two
implicit overlayfs features: "index_all" and "verify_lower".
The "index_all" feature creates an index on copy up of every file and
directory. The "verify_lower" feature uses the full index to detect
overlay filesystems inconsistencies on lookup, like redirect from
multiple upper dirs to the same lower dir.

NFS export can be enabled for non-upper mount with no index. However,
because lower layer redirects cannot be verified with the index, enabling
NFS export support on an overlay with no upper layer requires turning off
redirect follow (e.g. "redirect_dir=nofollow").

The full index may incur some overhead on mount time, especially when
verifying that lower directory file handles are not stale.

NFS export support, full index and consistency verification will be
implemented by following patches.

the lirc features ioctl for raw IR devices advertises two modes for

The lirc daemon now fails to detect a raw IR device, both for transmit
and receive.

To fix this, do not advertise the scancode mode in the lirc features

can still be used via the LIRC_SET_{REC,SEND}_MODE ioctl.

DAX is a coprocessor which resides on the SPARC M7 (DAX1) and M8
(DAX2) processor chips, and has direct access to the CPU's L3 caches
as well as physical memory. It can perform several operations on data
streams with various input and output formats.  This driver provides a
transport mechanism and has limited knowledge of the various opcodes
and data formats. A user space library provides high level services
and translates these into low level commands which are then passed
into the driver and subsequently the hypervisor and the coprocessor.
The library is the recommended way for applications to use the
coprocessor, and the driver interface is not intended for general use.

3214d01f13 KVM: PPC: Book3S: Provide information about hardware/firmware CVE workarounds
This adds a new ioctl, KVM_PPC_GET_CPU_CHAR, that gives userspace
information about the underlying machine's level of vulnerability
to the recently announced vulnerabilities CVE-2017-5715,
CVE-2017-5753 and CVE-2017-5754, and whether the machine provides
instructions to assist software to work around the vulnerabilities.

The ioctl returns two u64 words describing characteristics of the
CPU and required software behaviour respectively, plus two mask
words which indicate which bits have been filled in by the kernel,
for extensibility.  The bit definitions are the same as for the
new H_GET_CPU_CHARACTERISTICS hypercall.

There is also a new capability, KVM_CAP_PPC_GET_CPU_CHAR, which
indicates whether the new ioctl is available.

====================
pull-request: can-next 2018-01-16

this is a pull request for net-next/master consisting of 9 patches.

This is a series of patches, some of them initially by Franklin S Cooper
Jr, which was picked up by Faiz Abbas. Faiz Abbas added some patches
while working on this series, I contributed one as well.

The first two patches add support to CAN device infrastructure to limit
the bitrate of a CAN adapter if the used CAN-transceiver has a certain
maximum bitrate.

The remaining patches improve the m_can driver. They add support for
bitrate limiting to the driver, clean up the driver and add support for
runtime PM.

9b28a1102e dm thin: fix documentation relative to low water mark threshold
Fixes:
1. The use of "exceeds" when the opposite of exceeds, falls below,
was meant.
2. Properly speaking, a table can not exceed a threshold.

It emphasizes the important point, which is that it is the userspace
daemon's responsibility to check for low free space when a device
is resumed, since it won't get a special event indicating low free
space in that situation.

18a5bf2705 dm: add unstriped target
This device mapper "unstriped" target remaps and unstripes I/O so it
is issued solely on a single drive in a HW RAID0 or dm-striped target.

In a 4 drive HW RAID0 the striped target exposes 1/4th of the LBA range

to the 1 drive that was selected of the 4 drives in the HW RAID0.

This unstriped target is most useful for Intel NVMe drives that have
multiple cores but that do not have firmware control to pin separate LBA
ranges to each discrete cpu core.

Daniel Borkmann says:

====================
pull-request: bpf-next 2018-01-17

The following pull-request contains BPF updates for your *net-next* tree.

The main changes are:

1) Add initial BPF map offloading for nfp driver. Currently only
   programs were supported so far w/o being able to access maps.
   Offloaded programs are right now only allowed to perform map
   lookups, and control path is responsible for populating the
   maps. BPF core infrastructure along with nfp implementation is
   provided, from Jakub.

2) Various follow-ups to Josef's BPF error injections. More
   specifically that includes: properly check whether the error
   injectable event is on function entry or not, remove the percpu
   bpf_kprobe_override and rather compare instruction pointer
   with original one, separate error-injection from kprobes since
   it's not limited to it, add injectable error types in order to
   specify what is the expected type of failure, and last but not
   least also support the kernel's fault injection framework, all
   from Masami.

3) Various misc improvements and cleanups to the libbpf Makefile.
   That is, fix permissions when installing BPF header files, remove
   unused variables and functions, and also install the libbpf.h
   header, from Jesper.

4) When offloading to nfp JIT and the BPF insn is unsupported in the
   JIT, then reject right at verification time. Also fix libbpf with
   regards to ELF section name matching by properly treating the
   program type as prefix. Both from Quentin.

5) Add -DPACKAGE to bpftool when including bfd.h for the disassembler.
   This is needed, for example, when building libfd from source as
   bpftool doesn't supply a config.h for bfd.h. Fix from Jiong.

6) xdp_convert_ctx_access() is simplified since it doesn't need to
   set target size during verification, from Jesper.

7) Let bpftool properly recognize BPF_PROG_TYPE_CGROUP_DEVICE
   program types, from Roman.

8) Various functions in BPF cpumap were not declared static, from Wei.

9) Fix a double semicolon in BPF samples, from Luis.

c4e0842bf1 cgroup, docs: document the root cgroup behavior of cpu and io controllers
Currently, cgroups v2 documentation contains only a generic remark that
"How resource consumption in the root cgroup is governed is up to each
controller", which isn't really telling users much, who need to dig in the
code and / or commit messages to learn the exact behavior.

In cgroups v1 at least the blkio controller had its operation with respect
to competition between child threads and child cgroups documented in
blkio-controller.txt, with references to cfq-iosched.txt.
Also, cgroups v2 documentation describes v1 behavior of both cpu and
blkio controllers in an "Issues with v1" section.

Let's document this behavior also for cgroups v2 to make life easier for
users.

65e38583c3 Merge branch 'sev-v9-p2' of https://github.com/codomania/kvm
This part of Secure Encrypted Virtualization (SEV) patch series focuses on KVM
changes required to create and manage SEV guests.

SEV is an extension to the AMD-V architecture which supports running encrypted
virtual machine (VMs) under the control of a hypervisor. Encrypted VMs have their
pages (code and data) secured such that only the guest itself has access to
unencrypted version. Each encrypted VM is associated with a unique encryption key;
if its data is accessed to a different entity using a different key the encrypted
guest's data will be incorrectly decrypted, leading to unintelligible data.
This security model ensures that hypervisor will no longer able to inspect or
alter any guest code or data.

The key management of this feature is handled by a separate processor known as
the AMD Secure Processor (AMD-SP) which is present on AMD SOCs. The SEV Key
Management Specification (see below) provides a set of commands which can be
used by hypervisor to load virtual machine keys through the AMD-SP driver.

The patch series adds a new ioctl in KVM driver (KVM_MEMORY_ENCRYPT_OP). The
ioctl will be used by qemu to issue SEV guest-specific commands defined in Key
Management Specification.

The following links provide additional details:

858a43aae2 KVM: X86: use paravirtualized TLB Shootdown
Remote TLB flush does a busy wait which is fine in bare-metal
scenario. But with-in the guest, the vcpus might have been pre-empted or
blocked. In this scenario, the initator vcpu would end up busy-waiting
for a long amount of time; it also consumes CPU unnecessarily to wake
up the target of the shootdown.

This patch set adds support for KVM's new paravirtualized TLB flush;
remote TLB flush does not wait for vcpus that are sleeping, instead
KVM will flush the TLB as soon as the vCPU starts running again.

The improvement is clearly visible when the host is overcommitted; in this
case, the PV TLB flush (in addition to avoiding the wait on the main CPU)
prevents preempted vCPUs from stealing precious execution time from the
running ones.

Testing on a Xeon Gold 6142 2.6GHz 2 sockets, 32 cores, 64 threads,
so 64 pCPUs, and each VM is 64 vCPUs.

5855564c8a KVM: PPC: Book3S HV: Enable migration of decrementer register
This adds a register identifier for use with the one_reg interface
to allow the decrementer expiry time to be read and written by
userspace.  The decrementer expiry time is in guest timebase units
and is equal to the sum of the decrementer and the guest timebase.
(The expiry time is used rather than the decrementer value itself
because the expiry time is not constantly changing, though the
decrementer value is, while the guest vcpu is not running.)

Without this, a guest vcpu migrated to a new host will see its
decrementer set to some random value.  On POWER8 and earlier, the
decrementer is 32 bits wide and counts down at 512MHz, so the
guest vcpu will potentially see no decrementer interrupts for up
to about 4 seconds, which will lead to a stall.  With POWER9, the
decrementer is now 56 bits side, so the stall can be much longer
(up to 2.23 years) and more noticeable.

To help work around the problem in cases where userspace has not been
updated to migrate the decrementer expiry time, we now set the
default decrementer expiry at vcpu creation time to the current time
rather than the maximum possible value.  This should mean an
immediate decrementer interrupt when a migrated vcpu starts
running.  In cases where the decrementer is 32 bits wide and more
than 4 seconds elapse between the creation of the vcpu and when it
first runs, the decrementer would have wrapped around to positive
values and there may still be a stall - but this is no worse than
the current situation.  In the large-decrementer case, we are sure
to get an immediate decrementer interrupt (assuming the time from
vcpu creation to first run is less than 2.23 years) and we thus
avoid a very long stall.

1532d9e87e raid5-ppl: PPL support for disks with write-back cache enabled
In order to provide data consistency with PPL for disks with write-back
cache enabled all data has to be flushed to disks before next PPL
entry. The disks to be flushed are marked in the bitmap. It's modified
under a mutex and it's only read after PPL io unit is submitted.

A limitation of 64 disks in the array has been introduced to keep data
structures and implementation simple. RAID5 arrays with so many disks are
not likely due to high risk of multiple disks failure. Such restriction
should not be a real life limitation.

With write-back cache disabled next PPL entry is submitted when data write
for current one completes. Data flush defers next log submission so trigger
it when there are no stripes for handling found.

As PPL assures all data is flushed to disk at request completion, just
acknowledge flush request when PPL is enabled.

The Kryo CPUs are also affected by the Falkor 1003 errata, so
we need to do the same workaround on Kryo CPUs. The MIDR is
slightly more complicated here, where the PART number is not
always the same when looking at all the bits from 15 to 4. Drop
the lower 8 bits and just look at the top 4 to see if it's '2'
and then consider those as Kryo CPUs. This covers all the
combinations without having to list them all out.

Pull x86 pti updates from Thomas Gleixner:
 "This contains:

   - a PTI bugfix to avoid setting reserved CR3 bits when PCID is
     disabled. This seems to cause issues on a virtual machine at least
     and is incorrect according to the AMD manual.

   - a PTI bugfix which disables the perf BTS facility if PTI is
     enabled. The BTS AUX buffer is not globally visible and causes the
     CPU to fault when the mapping disappears on switching CR3 to user
     space. A full fix which restores BTS on PTI is non trivial and will
     be worked on.

   - PTI bugfixes for EFI and trusted boot which make sure that the user
     space visible page table entries have the NX bit cleared

   - removal of dead code in the PTI pagetable setup functions

   - add PTI documentation

   - add a selftest for vsyscall to verify that the kernel actually
     implements what it advertises.

   - a sysfs interface to expose vulnerability and mitigation
     information so there is a coherent way for users to retrieve the
     status.

   - the initial spectre_v2 mitigations, aka retpoline:

      + The necessary ASM thunk and compiler support

      + The ASM variants of retpoline and the conversion of affected ASM
        code

      + Make LFENCE serializing on AMD so it can be used as speculation
        trap

      + The RSB fill after vmexit

   - initial objtool support for retpoline

  As I said in the status mail this is the most of the set of patches
  which should go into 4.15 except two straight forward patches still on
  hold:

   - the retpoline add on of LFENCE which waits for ACKs

   - the RSB fill after context switch

  Both should be ready to go early next week and with that we'll have
  covered the major holes of spectre_v2 and go back to normality"

86f04f6400 Docs: dt: add devicetree binding for describing arm64 SDEI firmware
The Software Delegated Exception Interface (SDEI) is an ARM standard
for registering callbacks from the platform firmware into the OS.
This is typically used to implement RAS notifications, or from an
IRQ that has been promoted to a firmware-assisted NMI.

Add a new devicetree binding to describe the SDE firmware interface.

9be712ef46 drm/tegra: Changes for v4.16-rc1
The bulk of these changes are preparation work and addition of support
 for Tegra186. Currently only HDMI output (the primary output on Jetson
 TX2) is supported, but the hardware is also capable of doing DSI and
 DisplayPort.
 
 Tegra DRM now also uses the atomic commit helpers instead of the open-
 coded variant that was only doing half its job. As a bit of a byproduct
 of the Tegra186 support the driver also gained HDMI 2.0 as well as zpos
 property support.
 
 Along the way there are also a few patches to clean up a few things and
 fix minor issues.

da28512156 x86/spectre: Add boot time option to select Spectre v2 mitigation
Add a spectre_v2= option to select the mitigation used for the indirect
branch speculation vulnerability.

Currently, the only option available is retpoline, in its various forms.
This will be expanded to cover the new IBRS/IBPB microcode features.

The RETPOLINE_AMD feature relies on a serializing LFENCE for speculation
control. For AMD hardware, only set RETPOLINE_AMD if LFENCE is a
serializing instruction, which is indicated by the LFENCE_RDTSC feature.

[ tglx: Folded back the LFENCE/AMD fixes and reworked it so IBRS
  	integration becomes simple ]

f32ab75471 x86/PCI: Add "pci=big_root_window" option for AMD 64-bit windows
Only try to enable a 64-bit window on AMD CPUs when "pci=big_root_window"
is specified.

This taints the kernel because the new 64-bit window uses address space we
don't know anything about, and it may contain unreported devices or memory
that would conflict with the window.

The pci_amd_enable_64bit_bar() quirk that enables the window is specific to
AMD CPUs.  The generic solution would be to have the firmware enable the
window and describe it in the host bridge's _CRS method, or at least
describe it in the _PRS method so the OS would have the option of enabling
it.

d0807da78e livepatch: Remove immediate feature
Immediate flag has been used to disable per-task consistency and patch
all tasks immediately. It could be useful if the patch doesn't change any
function or data semantics.

However, it causes problems on its own. The consistency problem is
currently broken with respect to immediate patches.

func            a
patches         1i
                2i
                3

When the patch 3 is applied, only 2i function is checked (by stack
checking facility). There might be a task sleeping in 1i though. Such
task is migrated to 3, because we do not check 1i in
klp_check_stack_func() at all.

Coming atomic replace feature would be easier to implement and more
reliable without immediate.

Thus, remove immediate feature completely and save us from the problems.

Note that force feature has the similar problem. However it is
considered as a last resort. If used, administrator should not apply any
new live patches and should plan for reboot into an updated kernel.

The architectures would now need to provide HAVE_RELIABLE_STACKTRACE to
fully support livepatch.

ASoC: codecs: dmic: Make number of channels configurable
The DMIC DAI driver specifies a number of 1 to 8 channels for each DAI.
The actual number of mics can currently not be configured in the device
tree or audio glue, but is derived from the min/max channels of the CPU
and codec DAI. A typical CPU DAI has two or more channels, in consequence
a single mic is treated as a stereo/multi channel device, even though
only one channel carries audio data.

This change adds the option to specify the number of used DMIC channels
in the device tree. When specified this value overwrites the default
channels_max value of 8 in the snd_soc_dai_driver struct of the codec.

04b8eb7a4c symbol lookup: introduce dereference_symbol_descriptor()
dereference_symbol_descriptor() invokes appropriate ARCH specific
function descriptor dereference callbacks:
- dereference_kernel_function_descriptor() if the pointer is a
  kernel symbol;

- dereference_module_function_descriptor() if the pointer is a
  module symbol.

This is the last step needed to make '%pS/%ps' smart enough to
handle function descriptor dereference on affected ARCHs and
to retire '%pF/%pf'.

To refresh it:
  Some architectures (ia64, ppc64, parisc64) use an indirect pointer
  for C function pointers - the function pointer points to a function
  descriptor and we need to dereference it to get the actual function
  pointer.

  Function descriptors live in .opd elf section and all affected
  ARCHs (ia64, ppc64, parisc64) handle it properly for kernel and
  modules. So we, technically, can decide if the dereference is
  needed by simply looking at the pointer: if it belongs to .opd
  section then we need to dereference it.

  The kernel and modules have their own .opd sections, obviously,
  that's why we need to split dereference_function_descriptor()
  and use separate kernel and module dereference arch callbacks.

36bde81e23 docs: add index entry for networking/msg_zerocopy
Currently msg_zerocopy is not included in any toctree. Sphinx emits a
build warning to this effect. The other three rst files in
Documentation/networking are all indexed. We can add msg_zerocopy to the
toctree to enable navigation of the document via HTML kernel docs.

Add msg_zerocopy to the networking/ toctree.

This patch updates the documentation with the observations that led
to commit bdcf0a423e ("kernel: make groups_sort calling a
responsibility group_info allocators") and the new behaviour required.
Specifically that groups_sort() should be called on a new group_list
before set_groups() or set_current_groups() is called.

Pull  more x86 pti fixes from Thomas Gleixner:
 "Another small stash of fixes for fallout from the PTI work:

   - Fix the modules vs. KASAN breakage which was caused by making
     MODULES_END depend of the fixmap size. That was done when the cpu
     entry area moved into the fixmap, but now that we have a separate
     map space for that this is causing more issues than it solves.

   - Use the proper cache flush methods for the debugstore buffers as
     they are mapped/unmapped during runtime and not statically mapped
     at boot time like the rest of the cpu entry area.

   - Make the map layout of the cpu_entry_area consistent for 4 and 5
     level paging and fix the KASLR vaddr_end wreckage.

   - Use PER_CPU_EXPORT for per cpu variable and while at it unbreak
     nvidia gfx drivers by dropping the GPL export. The subject line of
     the commit tells it the other way around, but I noticed that too
     late.

   - Fix the ASM alternative macros so they can be used in the middle of
     an inline asm block.

   - Rename the BUG_CPU_INSECURE flag to BUG_CPU_MELTDOWN so the attack
     vector is properly identified. The Spectre mitigations will come
     with their own bug bits later"

9059a3493e kconfig: fix relational operators for bool and tristate symbols
Since commit 31847b67be ("kconfig: allow use of relations other than
(in)equality") it is possible to use relational operators in Kconfig
statements. However, those operators give unexpected results when
applied to bool/tristate values:

	(n < y) = y (correct)
	(m < y) = y (correct)
	(n < m) = n (wrong)

This happens because relational operators process bool and tristate
symbols as strings and m sorts before n. It makes little sense to do a
lexicographical compare on bool and tristate values though.

Documentation/kbuild/kconfig-language.txt states that expression can have
a value of 'n', 'm' or 'y' (or 0, 1, 2 respectively for calculations).
Let's make it so for relational comparisons with bool/tristate
expressions as well and document them. If at least one symbol is an
actual string then the lexicographical compare works just as before.

1dddd25125 x86/kaslr: Fix the vaddr_end mess
vaddr_end for KASLR is only documented in the KASLR code itself and is
adjusted depending on config options. So it's not surprising that a change
of the memory layout causes KASLR to have the wrong vaddr_end. This can map
arbitrary stuff into other areas causing hard to understand problems.

Remove the whole ifdef magic and define the start of the cpu_entry_area to
be the end of the KASLR vaddr range.

Add documentation to that effect.

f5a40711fa x86/mm: Set MODULES_END to 0xffffffffff000000
Since f06bdd4001 ("x86/mm: Adapt MODULES_END based on fixmap section size")
kasan_mem_to_shadow(MODULES_END) could be not aligned to a page boundary.

So passing page unaligned address to kasan_populate_zero_shadow() have two
possible effects:

1) It may leave one page hole in supposed to be populated area. After commit
  21506525fb ("x86/kasan/64: Teach KASAN about the cpu_entry_area") that
  hole happens to be in the shadow covering fixmap area and leads to crash:

 BUG: unable to handle kernel paging request at fffffbffffe8ee04
 RIP: 0010:check_memory_region+0x5c/0x190

 Call Trace:
  <NMI>
  memcpy+0x1f/0x50
  ghes_copy_tofrom_phys+0xab/0x180
  ghes_read_estatus+0xfb/0x280

  default_do_nmi+0x57/0x110
  do_nmi+0xf8/0x150
  end_repeat_nmi+0x1a/0x1e

Note, the crash likely disappeared after commit 92a0f81d89, which
changed kasan_populate_zero_shadow() call the way it was before
commit 21506525fb.

2) Attempt to load module near MODULES_END will fail, because
   __vmalloc_node_range() called from kasan_module_alloc() will hit the
   WARN_ON(!pte_none(*pte)) in the vmap_pte_range() and bail out with error.

To fix this we need to make kasan_mem_to_shadow(MODULES_END) page aligned
which means that MODULES_END should be 8*PAGE_SIZE aligned.

The whole point of commit f06bdd4001 was to move MODULES_END down if
NR_CPUS is big, so the cpu_entry_area takes a lot of space.
But since 92a0f81d89 ("x86/cpu_entry_area: Move it out of the fixmap")
the cpu_entry_area is no longer in fixmap, so we could just set
MODULES_END to a fixed 8*PAGE_SIZE aligned address.

dt-bindings: display: sun4i-drm: Add A83T pipeline
The A83T has two video pipelines in parallel that looks quite similar to
the other SoCs.

The video planes are handled through a controller called the mixer, and the
video signal is then passed to the timing controller (TCON).

And while there is two instances of the mixers and TCONs, they have a
significant number of differences. The TCONs are quite easy to deal with,
one is supposed to generate TV (in the broader term, so including things
like HDMI) signals, the other one LCD (so RGB, LVDS, DSI) signals. And
while they are called TCON0 and TCON1 in the A83t datasheet, newer SoCs
call them TCON-TV and TCON-LCD, which seems more appropriate.

However, the mixers differ mostly by their capabilities, with some features
being available only in the first one, or the number of planes they expose,
but also through their register layout. And while the capabilities could be
represented as properties, the register layout differences would need to
express all the registers offsets as properties, which is usually quite
bad. Especially since documentation on that hardware block is close to
non-existent and we don't even have the list of all those registers in the
first place.

So let's call them mixer 0 and 1 in our compatibles, even though the name
is pretty bad...

At the moment, we only have tested the code on a board that has a single
display output, so we're leaving the tcon-tv and mixer1 out.

cca10d58d2 printk: add console_msg_format command line option
0day and kernelCI automatically parse kernel log - basically some sort
of grepping using the pre-defined text patterns - in order to detect
and report regressions/errors. There are several sources they get the
kernel logs from:

a) dmesg or /proc/ksmg

   This is the preferred way. Because `dmesg --raw' (see later Note)
   and /proc/kmsg output contains facility and log level, which greatly
   simplifies grepping for EMERG/ALERT/CRIT/ERR messages.

b) serial consoles

   This option is harder to maintain, because serial console messages
   don't contain facility and log level.

This patch introduces a `console_msg_format=' command line option,
to switch between different message formatting on serial consoles.
For the time being we have just two options - default and syslog.
The "default" option just keeps the existing format. While the
"syslog" option makes serial console messages to appear in syslog
format [syslog() syscall], matching the `dmesg -S --raw' and
`cat /proc/kmsg' output formats:

- facility and log level
- time stamp (depends on printk_time/PRINTK_TIME)
- message

	<%u>[time stamp] text\n

NOTE: while Kevin and Fengguang talk about "dmesg --raw", it's actually
"dmesg -S --raw" that always prints messages in syslog format [per
Petr Mladek]. Running "dmesg --raw" may produce output in non-syslog
format sometimes. console_msg_format=syslog enables syslog format,
thus in documentation we mention "dmesg -S --raw", not "dmesg --raw".

Per Kevin Hilman:

: Right now we can get this info from a "dmesg --raw" after bootup,
: but it would be really nice in certain automation frameworks to
: have a kernel command-line option to enable printing of loglevels
: in default boot log.
:
: This is especially useful when ingesting kernel logs into advanced
: search/analytics frameworks (I'm playing with and ELK stack: Elastic
: Search, Logstash, Kibana).
:
: The other important reason for having this on the command line is that
: for testing linux-next (and other bleeding edge developer branches),
: it's common that we never make it to userspace, so can't even run
: "dmesg --raw" (or equivalent.)  So we really want this on the primary
: boot (serial) console.

Per Fengguang Wu, 0day scripts should quickly benefit from that
feature, because they will be able to switch to a more reliable
parsing, based on messages' facility and log levels [1]:

`#{grep} -a -E -e '^<[0123]>' -e '^kern  :(err   |crit  |alert |emerg )'

instead of doing text pattern matching

`#{grep} -a -F -f /lkp/printk-error-messages #{kmsg_file} |
      grep -a -v -E -f #{LKP_SRC}/etc/oops-pattern |
      grep -a -v -F -f #{LKP_SRC}/etc/kmsg-blacklist`

Merge tag 'at24-4.16-updates-for-wolfram' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux into i2c/for-4.16

"AT24 updates for 4.16 merge window

The driver has been converted to using regmap instead of raw i2c and
smbus calls which shrank the code significantly.

Device tree binding document has been cleaned up. Device tree support in
the driver has been improved and we now support all at24 models as well
as two new DT properties (no-read-rollover and wp-gpios).

We no longer user unreadable magic values for driver data as the way it
was implemented caused problems for some EEPROM models - we switched to
regular structs.

Aside from that, there's a bunch of coding style fixes and minor
improvements all over the place."

fe5b66c123 dt-bindings: update compatible string for ILI9225
This updates the compatible string for a no-name LCD panel to
"vot,v220hf01a-t", "ilitek,ili9225".

The original bindings [1] were the generic "ilitek,ili9225-2.2in-176x220"
because I could not find a datasheet. However, after some more research,
I finally found one, so the actual vendor and model name are now known.

This previous bindings have not made it to the mainline kernel yet, so
this is not breaking backwards compatibility.

This is also following the precedence of the ILI9322 bindings [2] by using
the pattern "vendor,specific-system-config", "vendor,ip-part";

Make the PM core handle DPM_FLAG_LEAVE_SUSPENDED directly for
devices whose "noirq", "late" and "early" driver callbacks are
invoked directly by it.

Namely, make it skip all of the system-wide resume callbacks for
such devices with DPM_FLAG_LEAVE_SUSPENDED set if they are in
runtime suspend during the "noirq" phase of system-wide suspend
(or analogous) transitions or the system transition under way is
a proper suspend (rather than anything related to hibernation) and
the device's wakeup settings are compatible with runtime PM (that
is, the device cannot generate wakeup signals at all or it is
allowed to wake up the system from sleep).

75e94645fc PM / core: Direct DPM_FLAG_SMART_SUSPEND optimization
Make the PM core avoid invoking the "late" and "noirq" system-wide
suspend (or analogous) callbacks provided by device drivers directly
for devices with DPM_FLAG_SMART_SUSPEND set that are in runtime
suspend during the "late" and "noirq" phases of system-wide suspend
(or analogous) transitions.  That is only done for devices without
any middle-layer "late" and "noirq" suspend callbacks (to avoid
confusing the middle layer if there is one).

The underlying observation is that runtime PM is disabled for devices
during the "late" and "noirq" system-wide suspend phases, so if they
remain in runtime suspend from the "late" phase forward, it doesn't
make sense to invoke the "late" and "noirq" callbacks provided by
the drivers for them (arguably, the device is already suspended and
in the right state).  Thus, if the remaining driver suspend callbacks
are to be invoked directly by the core, they can be skipped.

This change really makes it possible for, say, platform device
drivers to re-use runtime PM suspend and resume callbacks by
pointing ->suspend_late and ->resume_early, respectively (and
possibly the analogous hibernation-related callback pointers too),
to them without adding any extra "is the device already suspended?"
type of checks to the callback routines, as long as they will be
invoked directly by the core.
