ad40bdafb4 arm64: support __int128 with clang
Commit fb8722735f ("arm64: support __int128 on gcc 5+") added support
for arm64 __int128 with gcc with a version-conditional, but neglected to
enable this for clang, which in fact appears to support aarch64 __int128.
This commit therefore enables it if the compiler is clang, using the
same type of makefile conditional used elsewhere in the tree.

9478f1927e arm64: only advance singlestep for user instruction traps
Our arm64_skip_faulting_instruction() helper advances the userspace
singlestep state machine, but this is also called by the kernel BRK
handler, as used for WARN*().

Thus, if we happen to hit a WARN*() while the user singlestep state
machine is in the active-no-pending state, we'll advance to the
active-pending state without having executed a user instruction, and
will take a step exception earlier than expected when we return to
userspace.

Let's fix this by only advancing the state machine when skipping a user
instruction.

ed231ae384 arm64/kernel: rename module_emit_adrp_veneer->module_emit_veneer_for_adrp
Commit a257e02579 ("arm64/kernel: don't ban ADRP to work around
Cortex-A53 erratum #843419") introduced a function whose name ends with
"_veneer".

This clashes with commit bd8b22d288 ("Kbuild: kallsyms: ignore veneers
emitted by the ARM linker"), which removes symbols ending in "_veneer"
from kallsyms.

The problem was manifested as 'perf test -vvvvv vmlinux' failed,
correctly claiming the symbol 'module_emit_adrp_veneer' was present in
vmlinux, but not in kallsyms.

...
    ERR : 0xffff00000809aa58: module_emit_adrp_veneer not on kallsyms
...
    test child finished with -1
    ---- end ----
    vmlinux symtab matches kallsyms: FAILED!

Fix the problem by renaming module_emit_adrp_veneer to
module_emit_veneer_for_adrp.  Now the test passes.

We transiently switch to KERNEL_DS in compat_ptrace_gethbpregs() and

71c751f2a4 arm64: add sentinel to kpti_safe_list
We're missing a sentinel entry in kpti_safe_list. Thus is_midr_in_range_list()
can walk past the end of kpti_safe_list. Depending on the contents of memory,
this could erroneously match a CPU's MIDR, cause a data abort, or other bad
outcomes.

Add the sentinel entry to avoid this.

800cb2e553 arm64: kasan: avoid pfn_to_nid() before page array is initialized
In arm64's kasan_init(), we use pfn_to_nid() to find the NUMA node a
span of memory is in, hoping to allocate shadow from the same NUMA node.
However, at this point, the page array has not been initialized, and
thus this is bogus.

Since commit:

... accessing fields of the page array results in a boot time Oops(),

Let's fix this by using early_pfn_to_nid(), as other architectures do in
their kasan init code. Note that early_pfn_to_nid acquires the nid from
the memblock array, which we iterate over in kasan_init(), so this
should be fine.

24534b3511 arm64: assembler: add macros to conditionally yield the NEON under PREEMPT
Add support macros to conditionally yield the NEON (and thus the CPU)
that may be called from the assembler code.

In some cases, yielding the NEON involves saving and restoring a non
trivial amount of context (especially in the CRC folding algorithms),
and so the macro is split into three, and the code in between is only
executed when the yield path is taken, allowing the context to be preserved.
The third macro takes an optional label argument that marks the resume
path after a yield has been performed.

2dd8a62c64 linux/const.h: move UL() macro to include/linux/const.h
ARM, ARM64 and UniCore32 duplicate the definition of UL():

  #define UL(x) _AC(x, UL)

This is not actually arch-specific, so it will be useful to move it to a
common header.  Currently, we only have the uapi variant for
linux/const.h, so I am creating include/linux/const.h.

I also added _UL(), _ULL() and ULL() because _AC() is mostly used in
the form either _AC(..., UL) or _AC(..., ULL).  I expect they will be
replaced in follow-up cleanups.  The underscore-prefixed ones should

8f2af155b5 exec: pass stack rlimit into mm layout functions
Patch series "exec: Pin stack limit during exec".

Attempts to solve problems with the stack limit changing during exec
continue to be frustrated[1][2].  In addition to the specific issues
around the Stack Clash family of flaws, Andy Lutomirski pointed out[3]
other places during exec where the stack limit is used and is assumed to
be unchanging.  Given the many places it gets used and the fact that it
can be manipulated/raced via setrlimit() and prlimit(), I think the only
way to handle this is to move away from the "current" view of the stack
limit and instead attach it to the bprm, and plumb this down into the
functions that need to know the stack limits.  This series implements
the approach.

[1] 04e35f4495 ("exec: avoid RLIMIT_STACK races with prlimit()")
[2] 779f4e1c6c ("Revert "exec: avoid RLIMIT_STACK races with prlimit()"")
[3] to security@kernel.org, "Subject: existing rlimit races?"

This patch (of 3):

Since it is possible that the stack rlimit can change externally during
exec (either via another thread calling setrlimit() or another process
calling prlimit()), provide a way to pass the rlimit down into the
per-architecture mm layout functions so that the rlimit can stay in the
bprm structure instead of sitting in the signal structure until exec is
finalized.

54a702f705 kbuild: mark $(targets) as .SECONDARY and remove .PRECIOUS markers
GNU Make automatically deletes intermediate files that are updated
in a chain of pattern rules.

Example 1) %.dtb.o <- %.dtb.S <- %.dtb <- %.dts
Example 2) %.o <- %.c <- %.c_shipped

A couple of makefiles mark such targets as .PRECIOUS to prevent Make
from deleting them, but the correct way is to use .SECONDARY.

  .SECONDARY
    Prerequisites of this special target are treated as intermediate
    files but are never automatically deleted.

  .PRECIOUS
    When make is interrupted during execution, it may delete the target
    file it is updating if the file was modified since make started.
    If you mark the file as precious, make will never delete the file
    if interrupted.

Both can avoid deletion of intermediate files, but the difference is
the behavior when Make is interrupted; .SECONDARY deletes the target,
but .PRECIOUS does not.

The use of .PRECIOUS is relatively rare since we do not want to keep
partially constructed (possibly corrupted) targets.

Another difference is that .PRECIOUS works with pattern rules whereas
.SECONDARY does not.

  .PRECIOUS: $(obj)/%.lex.c

works, but

  .SECONDARY: $(obj)/%.lex.c

has no effect.  However, for the reason above, I do not want to use
.PRECIOUS which could cause obscure build breakage.

The targets specified as .SECONDARY must be explicit.  $(targets)
contains all targets that need to include .*.cmd files.  So, the
intermediates you want to keep are mostly in there.  Therefore, mark
$(targets) as .SECONDARY.  It means primary targets are also marked
as .SECONDARY, but I do not see any drawback for this.

I replaced some .SECONDARY / .PRECIOUS markers with 'targets'.  This
will make Kbuild search for non-existing .*.cmd files, but this is
not a noticeable performance issue.

167569343f ARM: SoC platform updates for 4.17
This release brings up a new platform based on the old ARM9 core: the
 Nuvoton NPCM is used as a baseboard management controller, competing
 with the better known ASpeed AST2xx series.
 
 Another important change is the addition of ARMv7-A based chips
 in mach-stm32. The older parts in this platform are ARMv7-M based
 microcontrollers, now they are expanding to general-purpose workloads.
 
 The other changes are the usual defconfig updates to enable additional
 drivers, lesser bugfixes. The largest updates as often are the ongoing
 OMAP cleanups, but we also have a number of changes for the older
 PXA and davinci platforms this time.
 
 For the Renesas shmobile/r-car platform, some new infrastructure
 is needed to make the watchdog work correctly.
 
 Supporting Multiprocessing on Allwinner A80 required a significant
 amount of new code, but is not doing anything unexpected.

b240b419db ARM: SoC device tree updates for 4.17
This is the usual set of changes for device trees, with over 700
 non-merged changesets. There is an ongoing set of dtc warning fixes and
 the usual bugfixes, cleanups and added device support.
 
 The most interesting bit as usual is support for new machines listed
 below:
 
 - The Allwinner H6 makes its debut with the Pine-H64 board, and we get
   two new machines based on its older siblings: the H5 based OrangePi
   Zero+ and the A64 based Teres-I Laptop from Olimex. On the 32-bit side,
   we add The Olimex som204 based on Allwinner A20, and the Banana Pi M2
   Zero development board (based on H2).
 
 - NVIDIA adds support for Tegra194 aka "Xavier", plus their p2972
   development board and p2888 CPU module.
 
 - The Nuvoton npcm750 is a BMC that was newly added, for now we only
   support running on the evaluation board.
 
 - STmicroelectronics stm32 gains support for the stm32mp157c and two
   evaluation boards.
 
 - The Toradex Colibri board family grows a few members based on the
   i.MX6ULL variant.
 
 - The Advantec DMS-BA16 is a Qseven module using the NXP i.MX6
   family of chips.
 
 - The Phytec phyBOARD Mira is a family of industrial boards based on
   i.MX6. For now, four models get added.
 
 - TI am335x based PDU-001 is an industrial embedded machine used for
   traffic monitoring
 
 - The Aspeed platform now supports running on the BMC on the Qualcomm
   Centriq 2400 server
 
 - Samsung Exynos4 based Galaxy S3 is a family of mobile phones Qualcomm
   msm8974 based Galaxy S5 is a rather different phone made by the same
   company.
 
 - The Xilinx Zynq and ZynqMP platforms now gained a lot of dts file
   for the various boards made by Xilinx themselves, as well as the
   Digilent Zybo Z7.
 
 - The ARM Versatile family now supports the "IB2" interface board.
 
 - The Renesas H2 based "Stout" and the H3 based Salvator-X are more
   evaluation boards named after a kind of beer, as most of them are.
   The r8a77980 (V3H) based "Condor" apparently doesn't follow that
   tradition. ;-)
 
 - ROC-RK3328-CC is a simple developement board from the Libre Computer
   Project, based on the Rockchips RK3328 SoC
 
 - Haiku is another development board plus Qseven module based on Rockchips
   RK3368 and made by Theobroma Systems.

23221d997b arm64 updates for 4.17
Nothing particularly stands out here, probably because people were tied
 up with spectre/meltdown stuff last time around. Still, the main pieces
 are:
 
 - Rework of our CPU features framework so that we can whitelist CPUs that
   don't require kpti even in a heterogeneous system
 
 - Support for the IDC/DIC architecture extensions, which allow us to elide
   instruction and data cache maintenance when writing out instructions
 
 - Removal of the large memory model which resulted in suboptimal codegen
   by the compiler and increased the use of literal pools, which could
   potentially be used as ROP gadgets since they are mapped as executable
 
 - Rework of forced signal delivery so that the siginfo_t is well-formed
   and handling of show_unhandled_signals is consolidated and made
   consistent between different fault types
 
 - More siginfo cleanup based on the initial patches from Eric Biederman
 
 - Workaround for Cortex-A55 erratum #1024718

667b24d049 arm64: Set CONFIG_MULTI_IRQ_HANDLER
arm has an optional MULTI_IRQ_HANDLER, which arm64 copied but didn't make
optional.  The multi irq handler infrastructure has been copied to generic
code selectable with a new config symbol. That symbol can be selected by
randconfig builds and can cause build breakage.

Introduce CONFIG_MULTI_IRQ_HANDLER as an intermediate step which prevents
the core config symbol from being selected. The arm64 local config symbol
will be removed once arm64 gets converted to the generic code.

642e7fd233 Merge branch 'syscalls-next' of git://git.kernel.org/pub/scm/linux/kernel/git/brodo/linux
Pull removal of in-kernel calls to syscalls from Dominik Brodowski:
 "System calls are interaction points between userspace and the kernel.
  Therefore, system call functions such as sys_xyzzy() or
  compat_sys_xyzzy() should only be called from userspace via the
  syscall table, but not from elsewhere in the kernel.

  At least on 64-bit x86, it will likely be a hard requirement from
  v4.17 onwards to not call system call functions in the kernel: It is
  better to use use a different calling convention for system calls
  there, where struct pt_regs is decoded on-the-fly in a syscall wrapper
  which then hands processing over to the actual syscall function. This
  means that only those parameters which are actually needed for a
  specific syscall are passed on during syscall entry, instead of
  filling in six CPU registers with random user space content all the
  time (which may cause serious trouble down the call chain). Those
  x86-specific patches will be pushed through the x86 tree in the near
  future.

  Moreover, rules on how data may be accessed may differ between kernel
  data and user data. This is another reason why calling sys_xyzzy() is
  generally a bad idea, and -- at most -- acceptable in arch-specific
  code.

  This patchset removes all in-kernel calls to syscall functions in the
  kernel with the exception of arch/. On top of this, it cleans up the
  three places where many syscalls are referenced or prototyped, namely
  kernel/sys_ni.c, include/linux/syscalls.h and include/linux/compat.h"

a90f590a1b mm: add ksys_mmap_pgoff() helper; remove in-kernel calls to sys_mmap_pgoff()
Using this helper allows us to avoid the in-kernel calls to the
sys_mmap_pgoff() syscall. The ksys_ prefix denotes that this function is
meant as a drop-in replacement for the syscall. In particular, it uses the
same calling convention as sys_mmap_pgoff().

This patch is part of a series which removes in-kernel calls to syscalls.
On this basis, the syscall entry path can be streamlined. For details, see

 board, as a lot of people where using that without the Exkavator baseboard.

65896545b6 arm64: uaccess: Fix omissions from usercopy whitelist
When the hardend usercopy support was added for arm64, it was
concluded that all cases of usercopy into and out of thread_struct
were statically sized and so didn't require explicit whitelisting
of the appropriate fields in thread_struct.

Testing with usercopy hardening enabled has revealed that this is
not the case for certain ptrace regset manipulation calls on arm64.
This occurs because the sizes of usercopies associated with the
regset API are dynamic by construction, and because arm64 does not
always stage such copies via the stack: indeed the regset API is
designed to avoid the need for that by adding some bounds checking.

This is currently believed to affect only the fpsimd and TLS
registers.

Because the whitelisted fields in thread_struct must be contiguous,
this patch groups them together in a nested struct.  It is also
necessary to be able to determine the location and size of that
struct, so rather than making the struct anonymous (which would
save on edits elsewhere) or adding an anonymous union containing
named and unnamed instances of the same struct (gross), this patch
gives the struct a name and makes the necessary edits to code that
references it (noisy but simple).

Care is needed to ensure that the new struct does not contain
padding (which the usercopy hardening would fail to protect).

For this reason, the presence of tp2_value is made unconditional,
since a padding field would be needed there in any case.  This pads
up to the 16-byte alignment required by struct user_fpsimd_state.

20b8547277 arm64: fpsimd: Split cpu field out from struct fpsimd_state
In preparation for using a common representation of the FPSIMD
state for tasks and KVM vcpus, this patch separates out the "cpu"
field that is used to track the cpu on which the state was most
recently loaded.

This will allow common code to operate on task and vcpu contexts
without requiring the cpu field to be stored at the same offset
from the FPSIMD register data in both cases.  This should avoid the
need for messing with the definition of those parts of struct
vcpu_arch that are exposed in the KVM user ABI.

The resulting change is also convenient for grouping and defining
the set of thread_struct fields that are supposed to be accessible
to copy_{to,from}_user(), which includes user_fpsimd_state but
should exclude the cpu field.  This patch does not amend the
usercopy whitelist to match: that will be addressed in a subsequent
patch.

7f170499f7 arm64: tlbflush: avoid writing RES0 bits
Several of the bits of the TLBI register operand are RES0 per the ARM
ARM, so TLBI operations should avoid writing non-zero values to these
bits.

This patch adds a macro __TLBI_VADDR(addr, asid) that creates the
operand register in the correct format and honors the RES0 bits.

dc6ed61d2f arm64: Add temporary ERRATA_MIDR_ALL_VERSIONS compatibility macro
MIDR_ALL_VERSIONS is changing, and won't have the same meaning
in 4.17, and the right thing to use will be ERRATA_MIDR_ALL_VERSIONS.

In order to cope with the merge window, let's add a compatibility
macro that will allow a relatively smooth transition, and that
can be removed post 4.17-rc1.
