b9299452cb arm64: dts: rockchip: add mmc nodes for rk3328 evaluation board
Rockchip's rk3328 evaluation board has 3 mmc controllers for
sdio/sdmmc/emmc, let's enable them.

6354a06cba Revert "arm64: dts: rockchip: Add basic cpu frequencies for RK3368"
This reverts commit 6f2dea1f5f.

Without accurate cpu regulators being set for boards this will wreak havoc
when cpufreq-dt begins to set new frequencies without adjusting the core
frequency.

Additionally the rk3368 has an unsolved issue in that it has two separate
cpu clusters with separate clock lines but only one cpu supply regulator
for both clusters, which causes even more problems.

While it seems that originally only one cluster was supposed to be active
at a time (big or little), talking with real users of the hardware
revealed that having all 8 cores accessible at 1.2GHz max is way more
liked than having 4 cores at 1.5GHz max. Such an approach needs changes
to cpufreq and/or opp though to control the two separate clock lines when
setting both clusters to the same frequencies.

In any case, having the OPPs in the dts at this point in time is
undesireable, so remove them again for now.

bb53c820c5 arm64: stacktrace: avoid listing stacktrace functions in stacktrace
The stacktraces always begin as follows:

  [<c00117b4>] save_stack_trace_tsk+0x0/0x98
  [<c0011870>] save_stack_trace+0x24/0x28
  ...

This is because the stack trace code includes the stack frames for
itself.  This is incorrect behaviour, and also leads to "skip" doing the
wrong thing (which is the number of stack frames to avoid recording.)

Perversely, it does the right thing when passed a non-current thread.
Fix this by ensuring that we have a known constant number of frames
above the main stack trace function, and always skip these.

This was fixed for arch arm by commit 3683f44c42 ("ARM: stacktrace:
avoid listing stacktrace functions in stacktrace")

dd198ce714 Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull namespace updates from Eric Biederman:
 "Life has been busy and I have not gotten half as much done this round
  as I would have liked. I delayed it so that a minor conflict
  resolution with the mips tree could spend a little time in linux-next
  before I sent this pull request.

  This includes two long delayed user namespace changes from Kirill
  Tkhai. It also includes a very useful change from Serge Hallyn that
  allows the security capability attribute to be used inside of user
  namespaces. The practical effect of this is people can now untar
  tarballs and install rpms in user namespaces. It had been suggested to
  generalize this and encode some of the namespace information
  information in the xattr name. Upon close inspection that makes the
  things that should be hard easy and the things that should be easy
  more expensive.

  Then there is my bugfix/cleanup for signal injection that removes the
  magic encoding of the siginfo union member from the kernel internal
  si_code. The mips folks reported the case where I had used FPE_FIXME
  me is impossible so I have remove FPE_FIXME from mips, while at the
  same time including a return statement in that case to keep gcc from
  complaining about unitialized variables.

  I almost finished the work to get make copy_siginfo_to_user a trivial
  copy to user. The code is available at:

     git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace.git neuter-copy_siginfo_to_user-v3

  But I did not have time/energy to get the code posted and reviewed
  before the merge window opened.

  I was able to see that the security excuse for just copying fields
  that we know are initialized doesn't work in practice there are buggy
  initializations that don't initialize the proper fields in siginfo. So
  we still sometimes copy unitialized data to userspace"

9b130ad5bb treewide: make "nr_cpu_ids" unsigned
First, number of CPUs can't be negative number.

Second, different signnnedness leads to suboptimal code in the following
cases:

1)
	kmalloc(nr_cpu_ids * sizeof(X));

"int" has to be sign extended to size_t.

2)
	while (loff_t *pos < nr_cpu_ids)

MOVSXD is 1 byte longed than the same MOV.

Other cases exist as well. Basically compiler is told that nr_cpu_ids
can't be negative which can't be deduced if it is "int".

This fix was intended for 4.13, but didn't get in because both
maintainers were on vacation.

Paul Mackerras:
 "It adds mutual exclusion between list_add_rcu and list_del_rcu calls
  on the kvm->arch.spapr_tce_tables list.  Without this, userspace could
  potentially trigger corruption of the list and cause a host crash or
  worse."

   the vmalloc space with a guard page for trapping stack overflows. One
   of the patches introduces THREAD_ALIGN and changes the generic
   alloc_thread_stack_node() to use this instead of THREAD_SIZE (no

 - Contiguous PTE hugetlb support re-enabled (after being reverted a
   couple of times). We now have the semantics agreed in the generic mm
   layer together with API improvements so that the architecture code can
   detect between contiguous and non-contiguous huge PTEs
 
 - Initial support for persistent memory on ARM: DC CVAP instruction
   exposed to user space (HWCAP) and the in-kernel pmem API implemented
 
 - raid6 improvements for arm64: faster algorithm for the delta syndrome
   and implementation of the recovery routines using Neon

 - PTE accessors converted from inline asm to cmpxchg so that we can

bb428921b7 KVM: arm/arm64: Fix guest external abort matching
The ARM-ARM has two bits in the ESR/HSR relevant to external aborts.
A range of {I,D}FSC values (of which bit 5 is always set) and bit 9 'EA'
which provides:
> an IMPLEMENTATION DEFINED classification of External Aborts.

This bit is in addition to the {I,D}FSC range, and has an implementation
defined meaning. KVM should always ignore this bit when handling external
aborts from a guest.

Remove the ESR_ELx_EA definition and rewrite its helper
kvm_vcpu_dabt_isextabt() to check the {I,D}FSC range. This merges
kvm_vcpu_dabt_isextabt() and the recently added is_abort_sea() helper.

 "Kernel side changes:

   - Add branch type profiling/tracing support. (Jin Yao)

   - Add the PERF_SAMPLE_PHYS_ADDR ABI to allow the tracing/profiling of
     physical memory addresses, where the PMU supports it. (Kan Liang)

   - Export some PMU capability details in the new
     /sys/bus/event_source/devices/cpu/caps/ sysfs directory. (Andi
     Kleen)

   - Aux data fixes and updates (Will Deacon)

   - kprobes fixes and updates (Masami Hiramatsu)

   - AMD uncore PMU driver fixes and updates (Janakarajan Natarajan)

  On the tooling side, here's a (limited!) list of highlights - there
  were many other changes that I could not list, see the shortlog and
  git history for details:

  UI improvements:

   - Implement a visual marker for fused x86 instructions in the
     annotate TUI browser, available now in 'perf report', more work
     needed to have it available as well in 'perf top' (Jin Yao)

     Further explanation from one of Jin's patches:

             │   ┌──cmpl   $0x0,argp_program_version_hook
       81.93 │   ├──je     20

             │   │↓ jmp    43
       11.47 │20:└─→cmpxch %esi,0x38a999(%rip)

     That means the cmpl+je is a fused instruction pair and they should
     be considered together.

   - Record the branch type and then show statistics and info about in
     callchain entries (Jin Yao)

     Example from one of Jin's patches:

        # perf record -g -j any,save_type
        # perf report --branch-history --stdio --no-children

                   __random random.c:295 (RET CROSS_2M cycles:9)

  namespaces support:

   - Add initial support for namespaces, using setns to access files in
     namespaces, grabbing their build-ids, etc. (Krister Johansen)

  perf trace enhancements:

   - Beautify pkey_{alloc,free,mprotect} arguments in 'perf trace'
     (Arnaldo Carvalho de Melo)

   - Add initial 'clone' syscall args beautifier in 'perf trace'
     (Arnaldo Carvalho de Melo)

   - Ignore 'fd' and 'offset' args for MAP_ANONYMOUS in 'perf trace'
     (Arnaldo Carvalho de Melo)

   - Beautifiers for the 'cmd' arg of several ioctl types, including:
     sound, DRM, KVM, vhost virtio and perf_events. (Arnaldo Carvalho de
     Melo)

   - Add PERF_SAMPLE_CALLCHAIN and PERF_RECORD_MMAP[2] to 'perf data'
     CTF conversion, allowing CTF trace visualization tools to show
     callchains and to resolve symbols (Geneviève Bastien)

   - Beautify the fcntl syscall, which is an interesting one in the
     sense that infrastructure had to be put in place to change the
     formatters of some arguments according to the value in a previous
     one, i.e. cmd dictates how arg and the syscall return will be
     formatted. (Arnaldo Carvalho de Melo

  perf stat enhancements:

   - Use group read for event groups in 'perf stat', reducing overhead
     when groups are defined in the event specification, i.e. when using
     {} to enclose a list of events, asking them to be read at the same
     time, e.g.: "perf stat -e '{cycles,instructions}'" (Jiri Olsa)

  pipe mode improvements:

   - Process tracing data in 'perf annotate' pipe mode (David
     Carrillo-Cisneros)

   - Add header record types to pipe-mode, now this command:

        $ perf record -o - -e cycles sleep 1 | perf report --stdio --header

     Will show the same as in non-pipe mode, i.e. involving a perf.data
     file (David Carrillo-Cisneros)

  Vendor specific hardware event support updates/enhancements:

   - Update POWER9 vendor events tables (Sukadev Bhattiprolu)

   - Add POWER9 PMU events Sukadev (Bhattiprolu)

   - Support additional POWER8+ PVR in PMU mapfile (Shriya)

   - Add Skylake server uncore JSON vendor events (Andi Kleen)

   - Support exporting Intel PT data to sqlite3 with python perf
     scripts, this is in addition to the postgresql support that was
     already there (Adrian Hunter)"

54f70f52e3 ARM: SoC fixes for 4.13
A couple of late-arriving fixes before final 4.13:
 
  - A few reverts of DT bindings on Allwinner for their ethernet
    driver. Discussion didn't converge, and since bindings are considered
    ABI it makes sense to revert instead of having to support two bindings
    long-term.
  - A fix to enumerate GPIOs properly on Marvell Armada AP806

a0ac89b572 arm64: dts: marvell: fix number of GPIOs in Armada AP806 description
The Armada AP806 has 20 pins, and therefore 20 GPIOs (from 0 to 19
included) and not 19 pins. Therefore, we fix the Device Tree
description for the GPIO controller.

Before this patch:

$ cat /sys/kernel/debug/pinctrl/f06f4000.system-controller:pinctrl/gpio-ranges
GPIO ranges handled:
0: mvebu-gpio GPIOS [0 - 19] PINS [0 - 19]
0: f06f4000.system-controller:gpio GPIOS [0 - 18] PINS [0 - 18]

After this patch:

$ cat /sys/kernel/debug/pinctrl/f06f4000.system-controller:pinctrl/gpio-ranges
GPIO ranges handled:
0: mvebu-gpio GPIOS [0 - 19] PINS [0 - 19]
0: f06f4000.system-controller:gpio GPIOS [0 - 19] PINS [0 - 19]

30d6e0a419 futex: Remove duplicated code and fix undefined behaviour
There is code duplicated over all architecture's headers for
futex_atomic_op_inuser. Namely op decoding, access_ok check for uaddr,
and comparison of the result.

Remove this duplication and leave up to the arches only the needed
assembly which is now in arch_futex_atomic_op_inuser.

This effectively distributes the Will Deacon's arm64 fix for undefined
behaviour reported by UBSAN to all architectures. The fix was done in
commit 5f16a046f8 (arm64: futex: Fix undefined behaviour with
FUTEX_OP_OPARG_SHIFT usage). Look there for an example dump.

And as suggested by Thomas, check for negative oparg too, because it was
also reported to cause undefined behaviour report.

Note that s390 removed access_ok check in d12a29703 ("s390/uaccess:
remove pointless access_ok() checks") as access_ok there returns true.
We introduce it back to the helper for the sake of simplicity (it gets
optimized away anyway).

a067d94d37 arm64: kaslr: Adjust the offset to avoid Image across alignment boundary
With 16KB pages and a kernel Image larger than 16MB, the current
kaslr_early_init() logic for avoiding mappings across swapper table
boundaries fails since increasing the offset by kimg_sz just moves the
problem to the next boundary.

This patch rounds the offset down to (1 << SWAPPER_TABLE_SHIFT) if the
Image crosses a PMD_SIZE boundary.

4a23e56ad6 arm64: kaslr: ignore modulo offset when validating virtual displacement
In the KASLR setup routine, we ensure that the early virtual mapping
of the kernel image does not cover more than a single table entry at
the level above the swapper block level, so that the assembler routines
involved in setting up this mapping can remain simple.

In this calculation we add the proposed KASLR offset to the values of
the _text and _end markers, and reject it if they would end up falling
in different swapper table sized windows.

However, when taking the addresses of _text and _end, the modulo offset
(the physical displacement modulo 2 MB) is already accounted for, and
so adding it again results in incorrect results. So disregard the modulo
offset from the calculation.

289d07a2dc arm64: mm: abort uaccess retries upon fatal signal
When there's a fatal signal pending, arm64's do_page_fault()
implementation returns 0. The intent is that we'll return to the
faulting userspace instruction, delivering the signal on the way.

However, if we take a fatal signal during fixing up a uaccess, this
results in a return to the faulting kernel instruction, which will be
instantly retried, resulting in the same fault being taken forever. As
the task never reaches userspace, the signal is not delivered, and the
task is left unkillable. While the task is stuck in this state, it can
inhibit the forward progress of the system.

To avoid this, we must ensure that when a fatal signal is pending, we
apply any necessary fixup for a faulting kernel instruction. Thus we
will return to an error path, and it is up to that code to make forward
progress towards delivering the fatal signal.

096622104e arm64: fpsimd: Prevent registers leaking across exec
There are some tricky dependencies between the different stages of
flushing the FPSIMD register state during exec, and these can race
with context switch in ways that can cause the old task's regs to
leak across.  In particular, a context switch during the memset() can
cause some of the task's old FPSIMD registers to reappear.

Disabling preemption for this small window would be no big deal for
performance: preemption is already disabled for similar scenarios
like updating the FPSIMD registers in sigreturn.

So, instead of rearranging things in ways that might swap existing
subtle bugs for new ones, this patch just disables preemption
around the FPSIMD state flushing so that races of this type can't
occur here.  This brings fpsimd_flush_thread() into line with other
code paths.

5ce93ab624 arm64: introduce separated bits for mm_context_t flags
Currently mm->context.flags field uses thread_info flags which is not
the best idea for many reasons. For example, mm_context_t doesn't need
most of thread_info flags. And it would be difficult to add new mm-related
flag if needed because it may easily interfere with TIF ones.

To deal with it, the new MMCF_AARCH32 flag is introduced for
mm_context_t->flags, where MMCF prefix stands for mm_context_t flags.
Also, mm_context_t flag doesn't require atomicity and ordering of the
access, so using set/clear_bit() is replaced with simple masks.

d8bdcff287 arm64: hugetlb: Add break-before-make logic for contiguous entries
It has become apparent that one has to take special care when modifying
attributes of memory mappings that employ the contiguous bit.

Both the requirement and the architecturally correct "Break-Before-Make"
technique of updating contiguous entries can be found described in:
ARM DDI 0487A.k_iss10775, "Misprogramming of the Contiguous bit",
page D4-1762.

The huge pte accessors currently replace the attributes of contiguous
pte entries in place thus can, on certain platforms, lead to TLB
conflict aborts or even erroneous results returned from TLB lookups.

This patch adds two helper functions -

* get_clear_flush(.) - clears a contiguous entry and returns the head
  pte (whilst taking care to retain dirty bit information that could
  have been modified by DBM).

* clear_flush(.) that clears a contiguous entry

A tlb invalidate is performed to then ensure that there is no
possibility of multiple tlb entries being present for the same region.

a88ce63b64 arm64: kexec: have own crash_smp_send_stop() for crash dump for nonpanic cores
Commit 0ee5941 : (x86/panic: replace smp_send_stop() with kdump friendly
version in panic path) introduced crash_smp_send_stop() which is a weak
function and can be overridden by architecture codes to fix the side effect
caused by commit f06e515 : (kernel/panic.c: add "crash_kexec_post_
notifiers" option).

 ARM64 architecture uses the weak version function and the problem is that
the weak function simply calls smp_send_stop() which makes other CPUs
offline and takes away the chance to save crash information for nonpanic
CPUs in machine_crash_shutdown() when crash_kexec_post_notifiers kernel
option is enabled.

 Calling smp_send_crash_stop() in machine_crash_shutdown() is useless
because all nonpanic CPUs are already offline by smp_send_stop() in this
case and smp_send_crash_stop() only works against online CPUs.

 The result is that secondary CPUs registers are not saved by
crash_save_cpu() and the vmcore file misreports these CPUs as being
offline.

 crash_smp_send_stop() is implemented to fix this problem by replacing the
existing smp_send_crash_stop() and adding a check for multiple calling to
the function. The function (strong symbol version) saves crash information
for nonpanic CPUs and machine_crash_shutdown() tries to save crash
information for nonpanic CPUs only when crash_kexec_post_notifiers kernel
option is disabled.

* crash_kexec_post_notifiers : false

  panic()
    __crash_kexec()
      machine_crash_shutdown()
        crash_smp_send_stop()    <= save crash dump for nonpanic cores

* crash_kexec_post_notifiers : true

  panic()
    crash_smp_send_stop()        <= save crash dump for nonpanic cores
    __crash_kexec()
      machine_crash_shutdown()
        crash_smp_send_stop()    <= just return.

0bb6f25a6e arm64: zynqmp: Add generic compatible string for I2C EEPROM
The at24 driver allows to register I2C EEPROM chips using different vendor
and devices, but the I2C subsystem does not take the vendor into account
when matching using the I2C table since it only has device entries.

But when matching using an OF table, both the vendor and device has to be
taken into account so the driver defines only a set of compatible strings
using the "atmel" vendor as a generic fallback for compatible I2C devices.

So add this generic fallback to the device node compatible string to make
the device to match the driver using the OF device ID table.

64c26841b3 arm64: Ignore hardware dirty bit updates in ptep_set_wrprotect()
ptep_set_wrprotect() is only called on CoW mappings which are private
(!VM_SHARED) with the pte either read-only (!PTE_WRITE && PTE_RDONLY) or
writable and software-dirty (PTE_WRITE && !PTE_RDONLY && PTE_DIRTY).
There is no race with the hardware update of the dirty state: clearing
of PTE_RDONLY when PTE_WRITE (a.k.a. PTE_DBM) is set. This patch removes
the code setting the software PTE_DIRTY bit in ptep_set_wrprotect() as
superfluous. A VM_WARN_ONCE is introduced in case the above logic is
wrong or the core mm code changes its use of ptep_set_wrprotect().

73e86cb03c arm64: Move PTE_RDONLY bit handling out of set_pte_at()
Currently PTE_RDONLY is treated as a hardware only bit and not handled
by the pte_mkwrite(), pte_wrprotect() or the user PAGE_* definitions.
The set_pte_at() function is responsible for setting this bit based on
the write permission or dirty state. This patch moves the PTE_RDONLY
handling out of set_pte_at into the pte_mkwrite()/pte_wrprotect()
functions. The PAGE_* definitions to need to be updated to explicitly
include PTE_RDONLY when !PTE_WRITE.

The patch also removes the redundant PAGE_COPY(_EXEC) definitions as
they are identical to the corresponding PAGE_READONLY(_EXEC).

c715b72c1b mm: revert x86_64 and arm64 ELF_ET_DYN_BASE base changes
Moving the x86_64 and arm64 PIE base from 0x555555554000 to 0x000100000000
broke AddressSanitizer.  This is a partial revert of:

  eab09532d4 ("binfmt_elf: use ELF_ET_DYN_BASE only for PIE")
  02445990a9 ("arm64: move ELF_ET_DYN_BASE to 4GB / 4MB")

The AddressSanitizer tool has hard-coded expectations about where
executable mappings are loaded.

The motivation for changing the PIE base in the above commits was to
avoid the Stack-Clash CVEs that allowed executable mappings to get too
close to heap and stack.  This was mainly a problem on 32-bit, but the
64-bit bases were moved too, in an effort to proactively protect those
systems (proofs of concept do exist that show 64-bit collisions, but
other recent changes to fix stack accounting and setuid behaviors will
minimize the impact).

The new 32-bit PIE base is fine for ASan (since it matches the ET_EXEC
base), so only the 64-bit PIE base needs to be reverted to let x86 and
arm64 ASan binaries run again.  Future changes to the 64-bit PIE base on
these architectures can be made optional once a more dynamic method for
dealing with AddressSanitizer is found.  (e.g.  always loading PIE into
the mmap region for marked binaries.)

fc9cc2797a Second Round of Renesas ARM64 Based SoC DT Updates for v4.14
* Add PFC device node to R-Car D3 (r8a77995)
 
   This is a step towards enabling devices that use multiplexed pins
   - including ethernet - on boards that use the r8a7796 SoC.
 
 * Add USB nodes to R-Car M3-W (r8a7796)
 
   This is a step towards enabling USB devices on boards that
   use the r8a7796 SoC.
 
 * Use newly added Gen-3 fallback compat string
 
   This is consistent with ongoing efforts to use per-generation
   fallback strings where appropriate across devices found
   on R-Car SoCs. The aim of the effort being to strike a balance
   between the limited information available about the compatibility
   of devices found on different SoCs and the desire to ease enabling
   devices on new SoCs.
 
   This has no run-time effect due to the presence of a per-SoC
   compat string.
 
 * Cleanup whitespace and extra LVDS port label
 
   Minor cleanups, no run-time effect.

522a6efef2 This pull request contains Broadcom ARM-based SoCs Device Tree changes for
4.14, please pull the following:
 
 - Eric moves the bcm2837 DT file from arm64 to arm because it created a maintenance
   problem and would have required either duplication or cross merges
 
 - Stefan changes how the pinmuxing is defined and pushes it at the board level
   to support Raspberry Pi Zero Wireless. He then adds supports for the actual
   Raspberry Pi Zero Wireless board along with binding documentation. Stefan
   also defines a proper SMP enable-method property and binding for BCM2836
   (Raspbery Pi 2)
 
 - Rafal describes the BCM5301X USB ports correctly in Device Tree such that
   it becomes possible to assign them to specific LED triggers (e.g: USB activity).
   He does the same thing for BCM53573 and defines default LED triggers for USB.
 
 - Jon provides a fix for Northstar Plus which consists in correctly defining
   the "dma-coherent" property for peripherals which are DMA coherent. He also
   does a bit of re-arrangement of the USB DT nodes and finally adds USB 3 PHY
   and host controller support for NorthStar Plus
 
 - Florian adds support for Broadcom's BCM947189ACDBMR reference board which is
   based on BCM47182/53573 and which supports external MoCA (BCM6802)
 
 - Ray fixes the wrong UART2 base address for Cygnus
 
 - Scott moves the v3d node in the proper unit address order and defines the correct
   UART alias for the BCM91130_entphn reference board to be UART3
 
 - Jason adds the DT node for the Cygnus Cortex-A9 Performance Monitoring Unit
 
 - Jonathan adds a bunch of additional peripherals to the Cygnus DTS include file:
   SDHCI, Keypad, SPI, DMA and pinmux configurations
 
 - Raveendra adds the Cygnus OHCI and EHCI Device Tree nodes

The percpu variables efi_fpsimd_state and efi_fpsimd_state_used,
used by the FPSIMD save/restore routines for EFI calls, are
unintentionally global.

There's no reason for anything outside fpsimd.c to touch these, so

place).

1d5bcbbd98 arm64: dts: rockchip: disable tx ipgap linecheck for rk3399 dwc3
RK3399 USB DWC3 controller has a issue that FS/LS devices not
recognized if inserted through USB 3.0 HUB. It's because that
the inter-packet delay between the SSPLIT token to SETUP token
is about 566ns, more then the USB spec requirement.

This patch adds a quirk "snps,dis-tx-ipgap-linecheck-quirk" to
disable the u2mac linestate check to decrease the SSPLIT token
to SETUP token inter-packet delay from 566ns to 466ns.

952111d7db arch: Remove spin_unlock_wait() arch-specific definitions
There is no agreed-upon definition of spin_unlock_wait()'s semantics,
and it appears that all callers could do just as well with a lock/unlock
pair.  This commit therefore removes the underlying arch-specific
arch_spin_unlock_wait() for all architectures providing them.

22e4ebb975 membarrier: Provide expedited private command
Implement MEMBARRIER_CMD_PRIVATE_EXPEDITED with IPIs using cpumask built
from all runqueues for which current thread's mm is the same as the
thread calling sys_membarrier. It executes faster than the non-expedited
variant (no blocking). It also works on NOHZ_FULL configurations.

Scheduler-wise, it requires a memory barrier before and after context
switching between processes (which have different mm). The memory
barrier before context switch is already present. For the barrier after
context switch:

* Our TSO archs can do RELEASE without being a full barrier. Look at
  x86 spin_unlock() being a regular STORE for example.  But for those
  archs, all atomics imply smp_mb and all of them have atomic ops in
  switch_mm() for mm_cpumask(), and on x86 the CR3 load acts as a full
  barrier.

* From all weakly ordered machines, only ARM64 and PPC can do RELEASE,
  the rest does indeed do smp_mb(), so there the spin_unlock() is a full
  barrier and we're good.

* ARM64 has a very heavy barrier in switch_to(), which suffices.

* PPC just removed its barrier from switch_to(), but appears to be
  talking about adding something to switch_mm(). So add a
  smp_mb__after_unlock_lock() for now, until this is settled on the PPC
  side.

Changes since v3:
- Properly document the memory barriers provided by each architecture.

Changes since v2:
- Address comments from Peter Zijlstra,
- Add smp_mb__after_unlock_lock() after finish_lock_switch() in
  finish_task_switch() to add the memory barrier we need after storing
  to rq->curr. This is much simpler than the previous approach relying
  on atomic_dec_and_test() in mmdrop(), which actually added a memory
  barrier in the common case of switching between userspace processes.
- Return -EINVAL when MEMBARRIER_CMD_SHARED is used on a nohz_full
  kernel, rather than having the whole membarrier system call returning
  -ENOSYS. Indeed, CMD_PRIVATE_EXPEDITED is compatible with nohz_full.
  Adapt the CMD_QUERY mask accordingly.

Changes since v1:
- move membarrier code under kernel/sched/ because it uses the
  scheduler runqueue,
- only add the barrier when we switch from a kernel thread. The case
  where we switch from a user-space thread is already handled by
  the atomic_dec_and_test() in mmdrop().
- add a comment to mmdrop() documenting the requirement on the implicit
  memory barrier.

Use newly added R-Car SATA Gen3 fallback compat string
in the DT of the r8a7795 SoC.

This should have no run-time effect as the driver matches against
the per-SoC compat string before the fallback compat string is considered.

111c074476 arm64: dts: salvator-common: Remove extra LVDS port label
The DU LVDS output is on port 3 on R8A7795 but on port 2 on R8A7796. The
lvds_connector label thus can't be defined in salvator-common.dtsi,
common to the two SoCs.

The lvds_connector label is meant for convenience to be referenced from
panel device tree files, such as r8a77xx-aa104xd12-panel.dtsi or
r8a77xx-aa121td01-panel.dtsi.  As those files are not included in any
device tree source, and the label never used elsewhere, we can simply
remove it. Out-of-tree patches that include panel device tree files can
then add a

	#define lvds_connector du_out_lvds0

before including the panel device tree file.

872784bffb Fourth Round of Renesas ARM Based SoC Fixes for v4.13
* Avoid audio_clkout naming conflict for salvator boards using
   Renesas R-Car Gen 3 SoCs
 
   Morimoto-san says "The clock name of "audio_clkout" is used by the
   Renesas sound driver.  This duplicated naming breaks its clock
   registering/unregistering.  Especially when unbind/bind it can't handle
   clkout correctly.  This patch renames "audio_clkout" to "audio-clkout" to
   avoid the naming conflict."

4fda1e7387 64bit Rockchip devicetree changes containing fixes for pinctrl typos
and the use of keep-power-in-suspend in non-sdio nodes as well as the
 removal of the deprecated num-slots property from dwmmc nodes.
 
 rk3328 gets support for spdif, io-domains and usb (including enablement
 of usb on the evaluation board), while rk3368 gains support for spdif.
 
 The biggest chunk of course aims for the rk3399 with a number of pcie
 changes, support for the mali gpu, a new power-domain, sdmmc support
 on the firefly board and dynamic-power-coefficients.
 
 The gru family also gets support for their quite central pwm regulators
 using the newly introduced vctrl regulator types.

Merge tag 'v4.14-rockchip-dts64-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip into next/dt64

Pull "Rockchip dts64 changes for 4.14" from Heiko Stübner:

64bit Rockchip devicetree changes containing fixes for pinctrl typos
and the use of keep-power-in-suspend in non-sdio nodes as well as the
removal of the deprecated num-slots property from dwmmc nodes.

rk3328 gets support for spdif, io-domains and usb (including enablement
of usb on the evaluation board), while rk3368 gains support for spdif.

The biggest chunk of course aims for the rk3399 with a number of pcie
changes, support for the mali gpu, a new power-domain, sdmmc support
on the firefly board and dynamic-power-coefficients.

The gru family also gets support for their quite central pwm regulators
using the newly introduced vctrl regulator types.

6421d89fab Renesas ARM64 Based SoC DT Updates for v4.14
* Add usb2.0 for R-Car H3 (r8a7795) ES2.0 SoC
 
 * Add R-Car D3 (r8a77995) SoC and Draak board support
 
   Adds minimal support for the R-Car D3 SoC and the Draak development
   board, allowing to boot from a ramdisk using a serial console.
 
 * Add Add VC6 clock generator to R-Car H3 (r8a7795)/Salvator-XS board
 
   The VC6 is an I2C-controlled programmable clock generator, used on the
   board to provide a display dot clock. Add it to DT.
 
 * Add missing second pair of DMA names to MSIOF nodes to
   R-Car M3-W (r8a7796) SoC
 
   MSIOF0 and MSIOF1 are tied to two DMA controllers through two pairs of
   DMA specifiers.  However, the second pair of corresponding DMA names was
   missing.
 
 * Add support for the DU to R-Car H3 (r8a7795) SoC
 
   Add a compatible string and VSP links to the DU node. The H3 ES1.x and H3
   ES2.0 are compatible save for the links to the VSPs that are described
   explicitly in DT, so there's no need for a new ES2-specific compatible
   string.
 
 * Enable HDMI on R-Car H3 (r8a7795) and M3-W (r8a7796) ULCB boards
 
 * Enable DU on R-Car M3-W (r8a7796) Salvator-X board
 
 * Enable I2C for DVFS on R-Car H3 (r8a7795) and M3-W (r8a7796) ULCB boards
 
 * Add Add DRIF support to R-Car H3 (r8a7795) and M3-W (r8a7796) SoCs
 
   Ramesh Shanmugasundaram says, "R-Car Gen3 DRIF is a SPI like receive only
   slave device."
 
 * Move CPG_AUDIO_CLK_I from board to soc files
 
   Geert Uytterhoeven says, "The definition of CPG_AUDIO_CLK_I is
   SoC-specific, not board-specific."
 
 * Add IMR-LX4 support to R-Car H3 (r8a7795) and M3-W (r8a7796) SoCs
 
   Sergei Shtylyov says, "The image renderer light extended 4 (IMR-LX4) or
   the distortion correction engine is a drawing processor with a simple
   instruction system capable of referencing data on an external memory as
   2D texture data and performing texture mapping and drawing with respect
   to any shape that is split into triangular objects."

30fec8268c arm64: dts: hi3660: enable idle states
There are two clusters on the Hi3660, the first one is Cortex-A53 based
and the other one is Cortex-A73 based. These two clusters have different
idle states.

Thanks to Daniel Lezcano's recent changes, the generic ARM cpuidle
driver can now support several clusters with different idle states, thus
supporting the big.Little architecture.

In addition to the WFI idle state which is the default shallowest state
for all ARM cpus, the Hi3660 supports the following states:

 - CA53 CPUs:
        - CPU_SLEEP:       CPU power off state
        - CLUSTER_SLEEP_0: Cluster power off state

 - CA73 CPUs:
        - CPU_NAP:         CPU retention state
        - CPU_SLEEP:       CPU power off state
        - CLUSTER_SLEEP_1: Cluster power off state

This patch adds the idle states description for the Hi3660 to the device
tree.

1. On hi6220, there are 15 tx_fifo dedicated for all EPs except EP0,
   while DT only provides tx_fifo settings for 6 EPs.  It results in the
   following annoying complaints from kernel.

   Besides of that, the total 1920 fifo entries isn't fully utilized.
   Endpoint Info Control block consumes 128 entries, g-rx-fifo-size
   is 512, and g-np-tx-fifo-size is 128.  So the fifi entries available
   for tx_fifo is: 1920 - 128 - 512 - 128 = 1152.  Considering that
   the minimal valid tx_fifo size for each EP is 16, it should be
   reasonable to allocate 1152 entries as: 128 x 8 + 16 x 7 = 1136 (only
   16 entries unused).  With this new setting, we can get more EPs to
   use while removing the above warning messages in the meantime.

2. Another consequence of above invalid g_tx_fifo_size parameter is that
   kernel driver will use values read from hardware register as the
   fall-back.  The value is 2048 for each EP fifo.  That's obviously
   invalid either, because even fifo entries for one EP exceeds the
   total entries 1920.  That's why we see the following fat warning from
   function dwc2_hsotg_init_fifo().  The new g-tx-fifo-size settings
   help to remove the warning as well.

872d8327ce arm64: add VMAP_STACK overflow detection
This patch adds stack overflow detection to arm64, usable when vmap'd stacks
are in use.

Overflow is detected in a small preamble executed for each exception entry,
which checks whether there is enough space on the current stack for the general
purpose registers to be saved. If there is not enough space, the overflow
handler is invoked on a per-cpu overflow stack. This approach preserves the
original exception information in ESR_EL1 (and where appropriate, FAR_EL1).

Task and IRQ stacks are aligned to double their size, enabling overflow to be
detected with a single bit test. For example, a 16K stack is aligned to 32K,
ensuring that bit 14 of the SP must be zero. On an overflow (or underflow),
this bit is flipped. Thus, overflow (of less than the size of the stack) can be
detected by testing whether this bit is set.

The overflow check is performed before any attempt is made to access the
stack, avoiding recursive faults (and the loss of exception information
these would entail). As logical operations cannot be performed on the SP
directly, the SP is temporarily swapped with a general purpose register
using arithmetic operations to enable the test to be performed.

This gives us a useful error message on stack overflow, as can be trigger with
the LKDTM overflow test:

12964443e8 arm64: add on_accessible_stack()
Both unwind_frame() and dump_backtrace() try to check whether a stack
address is sane to access, with very similar logic. Both will need
updating in order to handle overflow stacks.

Factor out this logic into a helper, so that we can avoid further
duplication when we add overflow stacks.

e3067861ba arm64: add basic VMAP_STACK support
This patch enables arm64 to be built with vmap'd task and IRQ stacks.

As vmap'd stacks are mapped at page granularity, stacks must be a multiple of
PAGE_SIZE. This means that a 64K page kernel must use stacks of at least 64K in
size.

To minimize the increase in Image size, IRQ stacks are dynamically allocated at
boot time, rather than embedding the boot CPU's IRQ stack in the kernel image.

This patch was co-authored by Ard Biesheuvel and Mark Rutland.
