99ce978759 arm64: dts: armada-3720-espressobin: Set mv88e6341 cpu port as RGMII-ID
The mv88e6341 ethernet switch needs the cpu port control register to be
set with TX and RX internal delay in order to work.

This fixes ethernet support on system booted via a bootloader that
has not already configured this register (e.g. mainline u-boot, or
vendor u-boot compiled without ethernet support).

Add the G12a (S905X2) based X96 Max board[1].

There is no branding for the manufacturer anywhere on the product, so it
took some digging[2] to find the manufacturer.  But since there's
nothing about the maker on the product I've left it out of the DT name
because 1) nobody will know that name and 2) keeps the DT filename
shorter.

12455e320e crypto: arm64/aes-neonbs - fix returning final keystream block
The arm64 NEON bit-sliced implementation of AES-CTR fails the improved
skcipher tests because it sometimes produces the wrong ciphertext.  The
bug is that the final keystream block isn't returned from the assembly
code when the number of non-final blocks is zero.  This can happen if
the input data ends a few bytes after a page boundary.  In this case the
last bytes get "encrypted" by XOR'ing them with uninitialized memory.

Fix the assembly code to return the final keystream block when needed.

6227cd12e5 crypto: arm64/crct10dif-ce - cleanup and optimizations
The x86, arm, and arm64 asm implementations of crct10dif are very
difficult to understand partly because many of the comments, labels, and
macros are named incorrectly: the lengths mentioned are usually off by a
factor of two from the actual code.  Many other things are unnecessarily
convoluted as well, e.g. there are many more fold constants than
actually needed and some aren't fully reduced.

This series therefore cleans up all these implementations to be much
more maintainable.  I also made some small optimizations where I saw
opportunities, resulting in slightly better performance.

This patch cleans up the arm64 version.

when the pack was picked into the Chrome OS kernel tree (allegedly
directly from the mailing list post) it had clock properties.

I presume that the clock should be there, so let's add it.

b972d2eaf0 ACPI / APEI: Use separate fixmap pages for arm64 NMI-like notifications
Now that ghes notification helpers provide the fixmap slots and
take the lock themselves, multiple NMI-like notifications can
be used on arm64.

These should be named after their notification method as they can't
all be called 'NMI'. x86's NOTIFY_NMI already is, change the SEA
fixmap entry to be called FIX_APEI_GHES_SEA.

Future patches can add support for FIX_APEI_GHES_SEI and
FIX_APEI_GHES_SDEI_{NORMAL,CRITICAL}.

Because all of ghes.c builds on both architectures, provide a
constant for each fixmap entry that the architecture will never
use.

d44f1b8dd7 arm64: KVM/mm: Move SEA handling behind a single 'claim' interface
To split up APEIs in_nmi() path, the caller needs to always be
in_nmi(). Add a helper to do the work and claim the notification.

When KVM or the arch code takes an exception that might be a RAS
notification, it asks the APEI firmware-first code whether it wants
to claim the exception. A future kernel-first mechanism may be queried
afterwards, and claim the notification, otherwise we fall through
to the existing default behaviour.

The NOTIFY_SEA code was merged before considering multiple, possibly
interacting, NMI-like notifications and the need to consider kernel
first in the future. Make the 'claiming' behaviour explicit.

Restructuring the APEI code to allow multiple NMI-like notifications
means any notification that might interrupt interrupts-masked
code must always be wrapped in nmi_enter()/nmi_exit(). This will
allow APEI to use in_nmi() to use the right fixmap entries.

Mask SError over this window to prevent an asynchronous RAS error
arriving and tripping 'nmi_enter()'s BUG_ON(in_nmi()).

0db5e02230 KVM: arm/arm64: Add kvm_ras.h to collect kvm specific RAS plumbing
To split up APEIs in_nmi() path, the caller needs to always be
in_nmi(). KVM shouldn't have to know about this, pull the RAS plumbing
out into a header file.

Currently guest synchronous external aborts are claimed as RAS
notifications by handle_guest_sea(), which is hidden in the arch codes
mm/fault.c. 32bit gets a dummy declaration in system_misc.h.

There is going to be more of this in the future if/when the kernel
supports the SError-based firmware-first notification mechanism and/or
kernel-first notifications for both synchronous external abort and
SError. Each of these will come with some Kconfig symbols and a
handful of header files.

Create a header file for all this.

This patch gives handle_guest_sea() a 'kvm_' prefix, and moves the
declarations to kvm_ras.h as preparation for a future patch that moves
the ACPI-specific RAS code out of mm/fault.c.

7d82602909 KVM: arm64: Forbid kprobing of the VHE world-switch code
On systems with VHE the kernel and KVM's world-switch code run at the
same exception level. Code that is only used on a VHE system does not
need to be annotated as __hyp_text as it can reside anywhere in the
kernel text.

__hyp_text was also used to prevent kprobes from patching breakpoint
instructions into this region, as this code runs at a different
exception level. While this is no longer true with VHE, KVM still
switches VBAR_EL1, meaning a kprobe's breakpoint executed in the
world-switch code will cause a hyp-panic.

358b28f09f arm/arm64: KVM: Allow a VCPU to fully reset itself
The current kvm_psci_vcpu_on implementation will directly try to
manipulate the state of the VCPU to reset it.  However, since this is
not done on the thread that runs the VCPU, we can end up in a strangely
corrupted state when the source and target VCPUs are running at the same
time.

Fix this by factoring out all reset logic from the PSCI implementation
and forwarding the required information along with a request to the
target VCPU.

e761a927bc KVM: arm/arm64: Reset the VCPU without preemption and vcpu state loaded
We have two ways to reset a vcpu:
- either through VCPU_INIT
- or through a PSCI_ON call

The first one is easy to reason about. The second one is implemented
in a more bizarre way, as it is the vcpu that handles PSCI_ON that
resets the vcpu that is being powered-on. As we need to turn the logic
around and have the target vcpu to reset itself, we must take some
preliminary steps.

Resetting the VCPU state modifies the system register state in memory,
but this may interact with vcpu_load/vcpu_put if running with preemption
disabled, which in turn may lead to corrupted system register state.

Address this by disabling preemption and doing put/load if required
around the reset logic.

48166e6ea4 y2038: add 64-bit time_t syscalls to all 32-bit architectures
This adds 21 new system calls on each ABI that has 32-bit time_t
today. All of these have the exact same semantics as their existing
counterparts, and the new ones all have macro names that end in 'time64'
for clarification.

This gets us to the point of being able to safely use a C library
that has 64-bit time_t in user space. There are still a couple of
loose ends to tie up in various areas of the code, but this is the
big one, and should be entirely uncontroversial at this point.

In particular, there are four system calls (getitimer, setitimer,
waitid, and getrusage) that don't have a 64-bit counterpart yet,
but these can all be safely implemented in the C library by wrapping
around the existing system calls because the 32-bit time_t they
pass only counts elapsed time, not time since the epoch. They
will be dealt with later.

8dabe7245b y2038: syscalls: rename y2038 compat syscalls
A lot of system calls that pass a time_t somewhere have an implementation
using a COMPAT_SYSCALL_DEFINEx() on 64-bit architectures, and have
been reworked so that this implementation can now be used on 32-bit
architectures as well.

The missing step is to redefine them using the regular SYSCALL_DEFINEx()
to get them out of the compat namespace and make it possible to build them
on 32-bit architectures.

Any system call that ends in 'time' gets a '32' suffix on its name for
that version, while the others get a '_time32' suffix, to distinguish
them from the normal version, which takes a 64-bit time argument in the
future.

In this step, only 64-bit architectures are changed, doing this rename
first lets us avoid touching the 32-bit architectures twice.

85738e05dc arm64: kvm: Unmask PMR before entering guest
Interrupts masked by ICC_PMR_EL1 will not be signaled to the CPU. This
means that hypervisor will not receive masked interrupts while running a
guest.

We need to make sure that all maskable interrupts are masked from the
time we call local_irq_disable() in the main run loop, and remain so
until we call local_irq_enable() after returning from the guest, and we
need to ensure that we see no interrupts at all (including pseudo-NMIs)
in the middle of the VM world-switch, while at the same time we need to
ensure we exit the guest when there are interrupts for the host.

We can accomplish this with pseudo-NMIs enabled by:
  (1) local_irq_disable: set the priority mask
  (2) enter guest: set PSTATE.I
  (3)              clear the priority mask
  (4) eret to guest
  (5) exit guest:  set the priotiy mask
                   clear PSTATE.I (and restore other host PSTATE bits)
  (6) local_irq_enable: clear the priority mask.

133d051863 arm64: Make PMR part of task context
In order to replace PSR.I interrupt disabling/enabling with ICC_PMR_EL1
interrupt masking, ICC_PMR_EL1 needs to be saved/restored when
taking/returning from an exception. This mimics the way hardware saves
and restores PSR.I bit in spsr_el1 for exceptions and ERET.

Add PMR to the registers to save in the pt_regs struct upon kernel entry,
and restore it before ERET. Also, initialize it to a sane value when
creating new tasks.

5870970b9a arm64: Fix HCR.TGE status for NMI contexts
When using VHE, the host needs to clear HCR_EL2.TGE bit in order
to interact with guest TLBs, switching from EL2&0 translation regime
to EL1&0.

However, some non-maskable asynchronous event could happen while TGE is
cleared like SDEI. Because of this address translation operations
relying on EL2&0 translation regime could fail (tlb invalidation,
userspace access, ...).

Fix this by properly setting HCR_EL2.TGE when entering NMI context and
clear it if necessary when returning to the interrupted context.

d23c808c6f arm64: ptdump: Don't iterate kernel page tables using PTRS_PER_PXX
When 52-bit virtual addressing is enabled for userspace
(CONFIG_ARM64_USER_VA_BITS_52=y), the kernel continues to utilise 48-bit
virtual addressing in TTBR1. Consequently, PTRS_PER_PGD reflects the
larger page table size for userspace and the pgd pointer for kernel page
tables is offset before being written to TTBR1.

This means that we can't use PTRS_PER_PGD to iterate over kernel page
tables unless we apply the same offset, which is fiddly to get right and
leads to some non-idiomatic walking code. Instead, just follow the usual
pattern when walking page tables by using a while loop driven by
pXd_offset() and pXd_addr_end().

83b944174a arm64: dts: hikey: Give wifi some time after power-on
Somewhere along recent changes to power control of the wl1835, power-on
became very unreliable on the hikey, failing like this:

wl1271_sdio: probe of mmc2:0001:1 failed with error -16
wl1271_sdio: probe of mmc2:0001:2 failed with error -16

After playing with some dt parameters and comparing to other users of
this chip, it turned out we need some power-on delay to make things
stable again. In contrast to those other users which define 200 ms, the
hikey would already be happy with 1 ms. Still, we use the safer 10 ms,
like on the Ultra96.

On systems with VHE the kernel and KVM's world-switch code run at the

need to be annotated as __hyp_text as it can reside anywhere in the
 kernel text.

__hyp_text was also used to prevent kprobes from patching breakpoint
instructions into this region, as this code runs at a different
exception level. While this is no longer true with VHE, KVM still
switches VBAR_EL1, meaning a kprobe's breakpoint executed in the
world-switch code will cause a hyp-panic.

Move the __hyp_text check in the kprobes blacklist so it applies on
VHE systems too, to cover the common code and guest enter/exit
assembly.

Commit 1598ecda7b ("arm64: kaslr: ensure randomized quantities are
clean to the PoC") added cache maintenance to ensure that global
variables set by the kaslr init routine are not wiped clean due to
cache invalidation occurring during the second round of page table
creation.

However, if kaslr_early_init() exits early with no randomization
being applied (either due to the lack of a seed, or because the user
has disabled kaslr explicitly), no cache maintenance is performed,
leading to the same issue we attempted to fix earlier, as far as the
module_alloc_base variable is concerned.

Note that module_alloc_base cannot be initialized statically, because
that would cause it to be subject to a R_AARCH64_RELATIVE relocation,
causing it to be overwritten by the second round of KASLR relocation
processing.

84a2ab25b1 arm64: imx8mq: select PM support
The ATF on the i.MX8MQ device disables all non-essential power
domains. For correct on-SoC peripheral operation we need both
the power domain driver and generic domains, so device driver
probe gets ordered behind the power domain controller driver.

Select those options, as those being absent can lead to very
hard to debug failures.

8336bdf12a crypto: arm64/crct10dif - register PMULL variants as separate algos
The arm64 CRC-T10DIF implementation either uses 8-bit or 64-bit
polynomial multiplication instructions, since the latter are
faster but not mandatory in the architecture.

Since that prevents us from testing both implementations on the
same system, let's expose both implementations to the crypto API,
with the priorities reflecting that the P64 version is the
preferred one if available.

d72b9d4acd crypto: arm64/crct10dif - revert to C code for short inputs
The SIMD routine ported from x86 used to have a special code path
for inputs < 16 bytes, which got lost somewhere along the way.
Instead, the current glue code aligns the input pointer to 16 bytes,
which is not really necessary on this architecture (although it
could be beneficial to performance to expose aligned data to the
the NEON routine), but this could result in inputs of less than
16 bytes to be passed in. This not only fails the new extended
tests that Eric has implemented, it also results in the code
reading past the end of the input, which could potentially result
in crashes when dealing with less than 16 bytes of input at the
end of a page which is followed by an unmapped page.

So update the glue code to only invoke the NEON routine if the
input is at least 16 bytes.

When the AES-CCM code was first added, the NEON register were saved

the scatterwalk in atomic context inside the kernel_neon_begin/end

This has been changed in the meantime, so switch to non-atomic
scatterwalks.

The NEON MAC calculation routine fails to handle the case correctly
where there is some data in the buffer, and the input fills it up
exactly. In this case, we enter the loop at the end with w8 == 0,
while a negative value is assumed, and so the loop carries on until
the increment of the 32-bit counter wraps around, which is quite
obviously wrong.

So omit the loop altogether in this case, and exit right away.

A couple of device tree fixes for the 5.0 cycle:

     The Linux clock driver uses the device node as the clock name if

(RZ/G2M) r8a774a1 SoCs.

This is was omitted from patches enabling DMA for other SCIF devices on the
same SoCs due to missing documentation.  However, it is regarded as a fix
as arguably those patches claim to add this feature.

Per-SoC patches are provided to ease backporting of this fix as the kernel

4daa001a17 arm64: dts: juno: Add cpu dynamic-power-coefficient information
A CPUfreq driver, like the scpi driver used on Juno boards, which
provide the Energy Model with power cost information via the PM_OPP
of_dev_pm_opp_get_cpu_power() function, do need the
dynamic-power-coefficient (C) in the device tree.

Method used to obtain the C value:

C is computed by measuring energy (E) consumption of a frequency domain
(FD) over a 10s runtime (t) sysbench workload running at each Operating
Performance Point (OPP) affine to 1 or 2 CPUs of that FD while the other
CPUs of the system are hotplugged out.

By definition all CPUs of a FD have the the same micro-architecture. An
OPP is characterized by a certain frequency (f) and voltage (V) value.
The corresponding power values (P) are calculated by dividing the delta
of the E values between the runs with 2 and 1 CPUs by t.

With n data tuples (P, f, V), n equal to number of OPPs for this
frequency domain, we can solve C by:

P = Pstat + Pdyn

P = Pstat + CV²f

Cx = (Px - P1)/(Vx²fx - V1²f1) with x = {2, ..., n}

The C value is the arithmetic mean out of {C2, ..., Cn}.

Since DVFS is broken on Juno r1, no dynamic-power-coefficient
information has been added to its dts file.

fa083b99eb arm64: dts: fast models: Add DTS fo Base RevC FVP
Fixed Virtual Platforms(FVP) Base RevC model is an emulated Arm platform
with GICv3, PCIe, SMMUv3 and various other features. These are available
free of charge on the Arm Community website at Arm Development
Platforms[1].

It resembles the Foundation Platform, which is a simple FVP that
includes an Armv8‑A AEM processor model but this has two cluster of four
cores, a CCI-550 interconnect, an SMMU and two PCI devices.

In order to enable development of software, let's add a description of
the Revison C version of Base platform.

The documentation for this FVP model is available @[2] for reference.

use the macros at all the places.

Since DTC doesn't even warn is any cells are missing, it's very hard to

Daniel Borkmann says:

====================
pull-request: bpf-next 2019-01-29

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

The main changes are:

1) Teach verifier dead code removal, this also allows for optimizing /
   removing conditional branches around dead code and to shrink the
   resulting image. Code store constrained architectures like nfp would
   have hard time doing this at JIT level, from Jakub.

2) Add JMP32 instructions to BPF ISA in order to allow for optimizing
   code generation for 32-bit sub-registers. Evaluation shows that this
   can result in code reduction of ~5-20% compared to 64 bit-only code
   generation. Also add implementation for most JITs, from Jiong.

3) Add support for __int128 types in BTF which is also needed for
   vmlinux's BTF conversion to work, from Yonghong.

4) Add a new command to bpftool in order to dump a list of BPF-related
   parameters from the system or for a specific network device e.g. in
   terms of available prog/map types or helper functions, from Quentin.

5) Add AF_XDP sock_diag interface for querying sockets from user
   space which provides information about the RX/TX/fill/completion
   rings, umem, memory usage etc, from Björn.

6) Add skb context access for skb_shared_info->gso_segs field, from Eric.

7) Add support for testing flow dissector BPF programs by extending
   existing BPF_PROG_TEST_RUN infrastructure, from Stanislav.

8) Split BPF kselftest's test_verifier into various subgroups of tests
   in order better deal with merge conflicts in this area, from Jakub.

9) Add support for queue/stack manipulations in bpftool, from Stanislav.

10) Document BTF, from Yonghong.

11) Dump supported ELF section names in libbpf on program load
    failure, from Taeung.

12) Silence a false positive compiler warning in verifier's BTF
    handling, from Peter.

13) Fix help string in bpftool's feature probing, from Prashant.

14) Remove duplicate includes in BPF kselftests, from Yue.

275f22148e ipc: rename old-style shmctl/semctl/msgctl syscalls
The behavior of these system calls is slightly different between
architectures, as determined by the CONFIG_ARCH_WANT_IPC_PARSE_VERSION
symbol. Most architectures that implement the split IPC syscalls don't set
that symbol and only get the modern version, but alpha, arm, microblaze,
mips-n32, mips-n64 and xtensa expect the caller to pass the IPC_64 flag.

For the architectures that so far only implement sys_ipc(), i.e. m68k,
mips-o32, powerpc, s390, sh, sparc, and x86-32, we want the new behavior
when adding the split syscalls, so we need to distinguish between the
two groups of architectures.

The method I picked for this distinction is to have a separate system call
entry point: sys_old_*ctl() now uses ipc_parse_version, while sys_*ctl()
does not. The system call tables of the five architectures are changed
accordingly.

As an additional benefit, we no longer need the configuration specific
definition for ipc_parse_version(), it always does the same thing now,
but simply won't get called on architectures with the modern interface.

A small downside is that on architectures that do set
ARCH_WANT_IPC_PARSE_VERSION, we now have an extra set of entry points
that are never called. They only add a few bytes of bloat, so it seems
better to keep them compared to adding yet another Kconfig symbol.
I considered adding new syscall numbers for the IPC_64 variants for
consistency, but decided against that for now.

4ab65ba7a5 ARM: add kexec_file_load system call number
A couple of architectures including arm64 already implement the
kexec_file_load system call, on many others we have assigned a system
call number for it, but not implemented it yet.

Adding the number in arch/arm/ lets us use the system call on arm64
systems in compat mode, and also reduces the number of differences
between architectures. If we want to implement kexec_file_load on ARM
in the future, the number assignment means that kexec tools can already
be built with the now current set of kernel headers.

78594b9599 ARM: add migrate_pages() system call
The migrate_pages system call has an assigned number on all architectures
except ARM. When it got added initially in commit d80ade7b32 ("ARM:
Fix warning: #warning syscall migrate_pages not implemented"), it was
intentionally left out based on the observation that there are no 32-bit
ARM NUMA systems.

However, there are now arm64 NUMA machines that can in theory run 32-bit
kernels (actually enabling NUMA there would require additional work)
as well as 32-bit user space on 64-bit kernels, so that argument is no
longer very strong.

Assigning the number lets us use the system call on 64-bit kernels as well
as providing a more consistent set of syscalls across architectures.

35a4f89cd4 arm64: dts: zcu100-revC: Give wifi some time after power-on
Somewhere along recent changes to power control of the wl1831, power-on
became very unreliable on the Ultra96, failing like this:

wl1271_sdio: probe of mmc2:0001:1 failed with error -16
wl1271_sdio: probe of mmc2:0001:2 failed with error -16

After playing with some dt parameters and comparing to other users of
this chip, it turned out we need some power-on delay to make things
stable again. In contrast to those other users which define 200 ms,
Ultra96 is already happy with 10 ms.

We currently hide the LORegion feature, and generate an UNDEF
if the guest dares using the corresponding registers. This is
a bit extreme, as ARMv8.1 guarantees the feature to be present.

The guest should check the feature register before doing anything,
but we could also give the guest some slack (read "allow the
guest to be a bit stupid").

So instead of unconditionnaly deliver an exception, let's
only do it when the host doesn't support LORegion at all (or
when the feature has been sanitized out), and treat the registers
as RAZ/WI otherwise (with the exception of LORID_EL1 being RO).

For devices attached to an IOMMU, translation between IOVA and physical
addresses is no longer 1:1 and dma-ranges should be specified to

On SDM845 the busses are implemented with 36 address bits, so dma-ranges
must be defined to reduce the size of the IOVA address space from the 48
bits supported by the SMMU. Without this DMA allocations may end up with
IOVAs outside the valid range, that gets truncated by the bus between
the device and its translation unit.

Also extend ranges to describe the available address space.

Xen-swiotlb hooks into the arm/arm64 arch code through a copy of the DMA
DMA mapping operations stored in the struct device arch data.

Switching arm64 to use the direct calls for the merged DMA direct /
swiotlb code broke this scheme.  Replace the indirect calls with
direct-calls in xen-swiotlb as well to fix this problem.

5d3b226ace arm64: dts: renesas: ulcb: use audio-graph-card
ULCB can use daughter board which is called as KingFisher.
It has extra sound interface, thus we want to use it.
But, basically, ALSA SoC can't use Multiple sound card with single
CPU sound interface (= SSI). Thus we need to use Single Sound Card
with multiple DAI interface.

To be easy to expand ULCB sound card on KingFisher, it is better to
use multi-dai-link style sound card on ULCB sound DT.

Now, "simple-audio-card" / "audio-graph-card" both can support
multi-dai-link style, but HDMI sound support (which is not yet supported
on ULCB) needs "audio-graph-card".
Using audio-graph-card is better selection.
This patch exchange current sound card to use it.

7eda14afb8 arm64: dts: renesas: r8a77990: ebisu: Fix EthernetAVB phy mode to rgmii
According to the R-Car Gen3 Hardware Manual Errata for Rev 1.00 of
August 24, 2018, the TX clock internal delay mode doesn't support
on R-Car E3. This patch fixes EthernetAVB phy mode to rgmii.

This is achieved by simply dropping the phy-mode property from
r8a77990-ebisu.dts as the default property for this for r8a77990,
as set in r8a77990.dtsi, is "rgmii".

similar to other arches.

memblocks_present() is a direct replacement of arm64_memory_present()

83504032e6 arm64: Remove asm/memblock.h
The arm64 asm/memblock.h header exists only to provide a function
prototype for arm64_memblock_init(), which is called only from
setup_arch().

Move the declaration into mmu.h, where it can live alongside other
init functions such as paging_init() and bootmem_init() without the
need for its own special header file.

846a415bf4 arm64: default NR_CPUS to 256
There are shipping arm64 platforms with 256 hardware threads. So that we
can make use of these with defconfig, bump the arm64 default NR_CPUS to
256.

At the same time, drop a redundant comment. We only have one default for
NR_CPUS, so there's nothing to sort.
