Pull staging/IIO updates from Greg KH:
 "Here is the big staging and IIO driver update for 4.18-rc1.

  It was delayed as I wanted to make sure the final driver deletions did
  not cause any major merge issues, and all now looks good.

  There are a lot of patches here, just over 1000. The diffstat summary
  shows the major changes here:

	1007 files changed, 16828 insertions(+), 227770 deletions(-)

  Because of this, we might be close to shrinking the overall kernel
  source code size for two releases in a row.

  There was loads of work in this release cycle, primarily:

   - tons of ks7010 driver cleanups

   - lots of mt7621 driver fixes and cleanups

   - most driver cleanups

   - wilc1000 fixes and cleanups

   - lots and lots of IIO driver cleanups and new additions

   - debugfs cleanups for all staging drivers

   - lots of other staging driver cleanups and fixes, the shortlog has
     the full details.

  but the big user-visable things here are the removal of 3 chunks of
  code:

   - ncpfs and ipx were removed on schedule, no one has cared about this
     code since it moved to staging last year, and if it needs to come
     back, it can be reverted.

   - lustre file system is removed.

     I've ranted at the lustre developers about once a year for the past
     5 years, with no real forward progress at all to clean things up
     and get the code into the "real" part of the kernel.

     Given that the lustre developers continue to work on an external
     tree and try to port those changes to the in-kernel tree every once
     in a while, this whole thing really really is not working out at
     all. So I'm deleting it so that the developers can spend the time
     working in their out-of-tree location and get things cleaned up
     properly to get merged into the tree correctly at a later date.

  Because of these file removals, you will have merge issues on some of
  these files (2 in the ipx code, 1 in the ncpfs code, and 1 in the
  atomisp driver). Just delete those files, it's a simple merge :)

  All of this has been in linux-next for a while with no reported
  problems"

Pull libnvdimm updates from Dan Williams:
 "This adds a user for the new 'bytes-remaining' updates to
  memcpy_mcsafe() that you already received through Ingo via the
  x86-dax- for-linus pull.

  Not included here, but still targeting this cycle, is support for
  handling memory media errors (poison) consumed via userspace dax
  mappings.

  Summary:

   - DAX broke a fundamental assumption of truncate of file mapped
     pages. The truncate path assumed that it is safe to disconnect a
     pinned page from a file and let the filesystem reclaim the physical
     block. With DAX the page is equivalent to the filesystem block.
     Introduce dax_layout_busy_page() to enable filesystems to wait for
     pinned DAX pages to be released. Without this wait a filesystem
     could allocate blocks under active device-DMA to a new file.

   - DAX arranges for the block layer to be bypassed and uses
     dax_direct_access() + copy_to_iter() to satisfy read(2) calls.
     However, the memcpy_mcsafe() facility is available through the pmem
     block driver. In order to safely handle media errors, via the DAX
     block-layer bypass, introduce copy_to_iter_mcsafe().

   - Fix cache management policy relative to the ACPI NFIT Platform
     Capabilities Structure to properly elide cache flushes when they
     are not necessary. The table indicates whether CPU caches are
     power-fail protected. Clarify that a deep flush is always performed
     on REQ_{FUA,PREFLUSH} requests"

Pull regulator updates from Mark Brown:
 "Quite a lot of core work this time around, though not 100% successful.

  We gained support for runtime mode changes thanks to David Collins and
  improved support for write only regulators (ones where we can't read
  back the configuration) from Douglas Anderson.

  There's been quite a bit of work from Linus Walleij on converting from
  specfying GPIOs by numbers to descriptors. Sadly the testing turned
  out to be less good than we had hoped and so a lot of this had to be
  reverted.

  We also have the start of updates to use coupled regulators from
  Maciej Purski, unfortunately there are further problems there so the
  last couple of patches have been reverted.

  We also have new drivers for BD71837 and SY8106A devices, SAW
  regulators on Qualcomm SPMI and dropped support for some preproduction
  chips that never made it to market from the AB8500 driver"

The problem here is that set_bit() and test_bit() take a bit number so
we should be passing 0 but instead we're passing (1 << 0) which leads to
a double shift.  It doesn't cause a runtime bug in the current code
because it's done consistently and we only set that one bit.

I decided to just re-use NVME_AER_NOTICE_NS_CHANGED instead of
introducing a new define for this.

A controller reset after a run time change of the CMB module parameter
breaks the driver. An 'on -> off' will have the driver use NULL for the
host memory queue, and 'off -> on' will use mismatched queue depth between
the device and the host.

We could fix both, but there isn't really a good reason to change this
at run time anyway, compared to at module load time, so this patch makes
parameter read-only after after modprobe.

We've been ignoring NVMe error status on queue creations. Fortunately they
are uncommon, but we should handle these anyway. This patch adds checks
for the a positive error return value that indicates an NVMe status.

If we do see a negative return, the controller isn't usable, so this
patch returns immediately in since we can't unwind that failure.

Pull arm64 updates from Catalin Marinas:
 "Apart from the core arm64 and perf changes, the Spectre v4 mitigation
  touches the arm KVM code and the ACPI PPTT support touches drivers/
  (acpi and cacheinfo). I should have the maintainers' acks in place.

  Summary:

   - Spectre v4 mitigation (Speculative Store Bypass Disable) support
     for arm64 using SMC firmware call to set a hardware chicken bit

   - ACPI PPTT (Processor Properties Topology Table) parsing support and
     enable the feature for arm64

   - Report signal frame size to user via auxv (AT_MINSIGSTKSZ). The
     primary motivation is Scalable Vector Extensions which requires
     more space on the signal frame than the currently defined
     MINSIGSTKSZ

   - ARM perf patches: allow building arm-cci as module, demote
     dev_warn() to dev_dbg() in arm-ccn event_init(), miscellaneous
     cleanups

   - cmpwait() WFE optimisation to avoid some spurious wakeups

   - L1_CACHE_BYTES reverted back to 64 (for performance reasons that
     have to do with some network allocations) while keeping
     ARCH_DMA_MINALIGN to 128. cache_line_size() returns the actual
     hardware Cache Writeback Granule

   - Turn LSE atomics on by default in Kconfig

   - Kernel fault reporting tidying

   - Some #include and miscellaneous cleanups"

     Also I just don't like VLA's, kernel developers hate it when
     compilers do things behind their back. It's as simple as that.

     I'm sorry that they even slipped in to begin with. Kudos to Laura
     Abbott for exorcising them.

Previously, mddev_put() had a couple different paths for freeing a
mddev, due to the fact that the kobject wasn't initialized when the
mddev was first allocated. If we move the kobject_init() to when it's
first allocated and just use kobject_add() later, we can clean all this
up.

This also removes a hack in mddev_put() to avoid freeing biosets under a
spinlock, which involved copying biosets on the stack after the reset
bioset_init() changes.

We can't just copy and clear a bio_set, use the bio helper to
setup a new bio_set with the settings from another one.

Commit 17c28958 ("arm64: Abstract syscallno manipulation") abstracts
out the pt_regs.syscallno value for a syscall cancelled by a tracer
as NO_SYSCALL, and provides helpers to set and check for this
condition.  However, the way this was implemented has the
unintended side-effect of disabling part of the syscall restart
logic.

This comes about because the second in_syscall() check in
do_signal() re-evaluates the "in a syscall" condition based on the
updated pt_regs instead of the original pt_regs.  forget_syscall()
is explicitly called prior to the second check in order to prevent
restart logic in the ret_to_user path being spuriously triggered,
which means that the second in_syscall() check always yields false.

This triggers a failure in
tools/testing/selftests/seccomp/seccomp_bpf.c, when using ptrace to
suppress a signal that interrups a nanosleep() syscall.

Misbehaviour of this type is only expected in the case where a
tracer suppresses a signal and the target process is either being
single-stepped or the interrupted syscall attempts to restart via
-ERESTARTBLOCK.

This patch restores the old behaviour by performing the
in_syscall() check only once at the start of the function.
