In the SoC branch we normally collect classic arch/arm/mach-* contents, i.e.
C code changes for SoC platforms. This release cycle the diffstat is quite
nice, in that we're removing 3x the amount of code that's being added.
The main reason for this is that there's a removal of camera drivers for
Freescale i.MX chips (driver was removed so the device registration isn't
needed any more). There's also removal of display initialization code for OMAP
that is no longer needed.
The rest are mostly minor tweaks and cleanups; constification on Samsung
platforms, cleanup of ux500 platform data, purge of other unused platform
data/device seutp on i.MX and other good stuff.
New SoC support this cycle is for two Allwinner platforms, H2+ and V3s.

- support for SMP guests
- a large rewrite of MMU emulation. KVM MIPS can now use MMU notifiers
to support copy-on-write, KSM, idle page tracking, swapping, ballooning
and everything else. KVM_CAP_READONLY_MEM is also supported, so that
writes to some memory regions can be treated as MMIO. The new MMU also
paves the way for hardware virtualization support.

- some refactoring of nested VMX entry/exit code, preparing for live
migration support of nested hypervisors
- expose yet another AVX512 CPUID bit
- host-to-guest PTP support
- refactoring of interrupt injection, with some optimizations thrown in
and some duct tape removed.
- remove lazy FPU handling
- optimizations of user-mode exits
- optimizations of vcpu_is_preempted() for KVM guests

Here is the big tty/serial driver patchset for 4.11-rc1.
Not much here, but a lot of little fixes and individual serial driver
updates all over the subsystem. Majority are for the sh-sci driver and
platform (the arch-specific changes have acks from the maintainer).
The start of the "serial bus" code is here as well, but nothing is
converted to use it yet. That work is still ongoing, hopefully will
start to show up across different subsystems for 4.12 (bluetooth is one
major place that will be used.)
All of these have been in linux-next for a while with no reported
issues.

Pull rodata updates from Kees Cook:
"This renames the (now inaccurate) DEBUG_RODATA and related
SET_MODULE_RONX configs to the more sensible STRICT_KERNEL_RWX and
STRICT_MODULE_RWX"
* tag 'rodata-v4.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux:
arch: Rename CONFIG_DEBUG_RODATA and CONFIG_DEBUG_MODULE_RONX
arch: Move CONFIG_DEBUG_RODATA and CONFIG_SET_MODULE_RONX to be common
Core changes:
- Switch the generic pin config argument from 16 to 24 bits,
only use 8 bits for the configuration type. We might need to
encode more information about a certain setting than we need
to encode different generic settings.
- Add a cross-talk API to the pin control GPIO back-end,
utilizing pinctrl_gpio_set_config() from GPIO drivers that
want to set up a certain pin configuration in the back-end.
This also includes the .set_config() refactoring of the
GPIO chips, so that they pass a generic configuration for
things like debouncing and single ended (typically open
drain). This change has also been merged in an immutable
branch to the GPIO tree.
- Take hogs with a delayed work, so that we finalize probing
a pin controller before trying to get any hogs.
- For pin controllers putting all group and function definitions
into the device tree, we now have generic code to deal with
this and it is used in two drivers so far.
- Simplifications of the pin request conflict check.
- Make dt_free_map() optional.
Updates to drivers:
- pinctrl-single now use the generic helpers to generate dynamic
group and function tables from the device tree.
- Texas Instruments IOdelay configuration driver add-on to
pinctrl-single.
- i.MX: use radix trees to store groups and functions, use the new
generic group and function helpers to manage them.
- Intel: add support for hardware debouncing and 1K pull-down.
New subdriver for the Gemini Lake SoC.
- Renesas SH-PFC: drive strength and bias support, CAN bus muxing,
MSIOF, SDHI, HSCIF for r8a7796. Gyro-ADC supporton r8a7791.
- Aspeed: use syscon cross-dependencies to set up related bits in
the LPC host controller and display controller.
- Aspeed: finalize G4 and G5 support. Fix mux configuration on
GPIOs. Add banks Y, Z, AA, AB and AC.
- AMD: support additional GPIO.
- STM32: set this controller to strict muxing mode.
STM32H743 MCU support.
- Allwinner sunxi: deep simplifications on how to support
subvariants of SoCs without adding to much SoC-specific data
for each subvariant, especially for sun5i variants. New driver
for V3s SoCs. New driver for the H5 SoC. Support A31/A31s
variants with the new variant framework.
- Mvebu: simplifications to use a MMIO and regmap abstraction.
New subdrivers for the 98DX3236, 98DX5241 SoCs.
- Samsung Exynos: delete Exynos4415 support. Add crosstalk to the
SoC driver to access regmaps. Add infrastructure for pin-bank
retention control. Clean out the pin retention control from
arch/arm/mach-exynos and arch/arm/mach-s5p and put it properly
in the Samsung pin control driver(s).
- Meson: add HDMI HPD/DDC pins. Add pwm_ao_b pin.
- Qualcomm: use raw spinlock variants: this makes the qualcomm
driver realtime-safe.

Pull exception table module split from Paul Gortmaker:
"Final extable.h related changes.
This completes the separation of exception table content from the
module.h header file. This is achieved with the final commit that
removes the one line back compatible change that sourced extable.h
into the module.h file.
The commits are unchanged since January, with the exception of a
couple Acks that came in for the last two commits a bit later. The
changes have been in linux-next for quite some time[1] and have got
widespread arch coverage via toolchains I have and also from
additional ones the kbuild bot has.
Maintaners of the various arch were Cc'd during the postings to
lkml[2] and informed that the intention was to take the remaining arch
specific changes and lump them together with the final two non-arch
specific changes and submit for this merge window.
The ia64 diffstat stands out and probably warrants a mention. In an
earlier review, Al Viro made a valid comment that the original header
separation of content left something to be desired, and that it get
fixed as a part of this change, hence the larger diffstat"

Currently, there's no good way to test for the presence of
set_memory_ro/rw/x/nx() helpers implemented by archs such as
x86, arm, arm64 and s390.
There's DEBUG_SET_MODULE_RONX and DEBUG_RODATA, however both
don't really reflect that: set_memory_*() are also available
even when DEBUG_SET_MODULE_RONX is turned off, and DEBUG_RODATA
is set by parisc, but doesn't implement above functions. Thus,
add ARCH_HAS_SET_MEMORY that is selected by mentioned archs,
where generic code can test against this.
This also allows later on to move DEBUG_SET_MODULE_RONX out of
the arch specific Kconfig to define it only once depending on
ARCH_HAS_SET_MEMORY.

The rtc-m48t86 driver can now handle its own resources and do the
read/write operations internally.
Pass the necessary resources to the driver and remove the m48t86_ops
platform data.
Remove the, then unnecessary, static remapping for the registers.

Pull power management updates from Rafael Wysocki:
"The majority of changes go into the Operating Performance Points (OPP)
framework and cpufreq this time, followed by devfreq and some
scattered updates all over.
The OPP changes are mostly related to switching over from RCU-based
synchronization, that turned out to be overly complicated and
problematic, to reference counting using krefs.
In the cpufreq land there are core cleanups, documentation updates, a
new driver for Broadcom BMIPS SoCs, a new cpufreq-dt sub-driver for TI
SoCs that require special handling, ARM64 SoCs support for the qoriq
driver, intel_pstate updates, powernv driver update and assorted
fixes.
The devfreq changes are mostly fixes related to the sysfs interface
and some Exynos drivers updates.
Apart from that, the cpuidle menu governor will support per-CPU PM QoS
constraints for the wakeup latency now, some bugs in the wakeup IRQs
framework are fixed, the generic power domains framework should handle
asynchronous invocations of *noirq suspend/resume callbacks from now
on, the analyze_suspend.py script is updated and there is a new tool
for intel_pstate diagnostics.

The purpose of the KVM_SET_SIGNAL_MASK API is to let userspace "kick"
a VCPU out of KVM_RUN through a POSIX signal. A signal is attached
to a dummy signal handler; by blocking the signal outside KVM_RUN and
unblocking it inside, this possible race is closed:
VCPU thread service thread
--------------------------------------------------------------
check flag
set flag
raise signal
(signal handler does nothing)
KVM_RUN
However, one issue with KVM_SET_SIGNAL_MASK is that it has to take
tsk->sighand->siglock on every KVM_RUN. This lock is often on a
remote NUMA node, because it is on the node of a thread's creator.
Taking this lock can be very expensive if there are many userspace
exits (as is the case for SMP Windows VMs without Hyper-V reference
time counter).
As an alternative, we can put the flag directly in kvm_run so that
KVM can see it:
VCPU thread service thread
--------------------------------------------------------------
raise signal
signal handler
set run->immediate_exit
KVM_RUN
check run->immediate_exit

the object size checks are moved outside the access_ok() so that bad

copy_from_user() failure path.
This makes the same change for arm, with attention given to possibly

Recently a new dm_op[1] hypercall was added to Xen to provide a mechanism
for restricting device emulators (such as QEMU) to a limited set of
hypervisor operations, and being able to audit those operations in the
kernel of the domain in which they run.
This patch adds IOCTL_PRIVCMD_DM_OP as gateway for __HYPERVISOR_dm_op.
NOTE: There is no requirement for user-space code to bounce data through
locked memory buffers (as with IOCTL_PRIVCMD_HYPERCALL) since
privcmd has enough information to lock the original buffers
directly.

Most of them got the CPU interface size wrong (4kB, while it should
be 8kB), except for both keystone platforms which got the control
interface wrong (4kB instead of 8kB).
In a few cases where I knew for sure what implementation was used,
I've added the "arm,gic-400" compatible string. I'm 99% sure that
this is what everyone is using, but short of having the TRM for
all the other SoCs, I've left them alone.

When hardware flow-control is disabled, manual toggling of the UART's
reset line (RTS) using userland applications (e.g. stty) is not
possible, since the ASC IP does not provide this functionality in the
same was as some other IPs do. Thus, we have to do this manually.
This patch configures the UART RTS line as a GPIO for manipulation
within the UART driver when HW flow-control is not enabled.

The ARM bit sliced AES core code uses the IV buffer to pass the final
keystream block back to the glue code if the input is not a multiple of
the block size, so that the asm code does not have to deal with anything
except 16 byte blocks. This is done under the assumption that the outgoing
IV is meaningless anyway in this case, given that chaining is no longer
possible under these circumstances.
However, as it turns out, the CCM driver does expect the IV to retain
a value that is equal to the original IV except for the counter value,
and even interprets byte zero as a length indicator, which may result
in memory corruption if the IV is overwritten with something else.
So use a separate buffer to return the final keystream block.

cputime_t is now only used by two architectures:
* powerpc (when CONFIG_VIRT_CPU_ACCOUNTING_NATIVE=y)
* s390
And since the core doesn't use it anymore, we don't need any arch support
from the others. So we can remove their stub implementations.
A final cleanup would be to provide an efficient pure arch
implementation of cputime_to_nsec() for s390 and powerpc and finally
remove include/linux/cputime.h .

The physical pins from the SoC are in a sense belonging to the
PHY device (AB8500 USB) rather than the MUSB USB IP block.
The driver definately assumes so: before this change it
complains that it cannot control the pins it is using:
abx5x0-usb ab8500-usb.0: could not get/set default pinstate
After this patch the warning goes away.

So we rename the file below:

Because DTS conversion of this device was just introduced in 4.9, Debian

When we fault in a page, we flush it to the PoC (Point of Coherency)
if the faulting vcpu has its own caches off, so that it can observe
the page we just brought it.
But if the vcpu has its caches on, we skip that step. Bad things
happen when *another* vcpu tries to access that page with its own
caches disabled. At that point, there is no garantee that the
data has made it to the PoC, and we access stale data.
The obvious fix is to always flush to PoC when a page is faulted
in, no matter what the state of the vcpu is.

It is used to identify the cpu for registers access.

Similarly, VM that supports Affinity Level 3 that is required for AArch64

for ICC_CTLR_EL1.A3V compatibility.
The arch/arm64/kvm/vgic-sys-reg-v3.c handles read and write of VGIC

For AArch32 mode, arch/arm/kvm/vgic-v3-coproc.c file is created but
