      Pull arm64 fixes from Catalin Marinas:
      
       - Ensure that the compiler and linker versions are aligned so that ld
         doesn't complain about not understanding a .note.gnu.property section
         (emitted when pointer authentication is enabled).
      
       - Force -mbranch-protection=none when the feature is not enabled, in
         case a compiler may choose a different default value.
      
       - Remove CONFIG_DEBUG_ALIGN_RODATA. It was never in defconfig and
         rarely enabled.
      
       - Fix checking 16-bit Thumb-2 instructions checking mask in the
         emulation of the SETEND instruction (it could match the bottom half
         of a 32-bit Thumb-2 instruction).

       "The bulk of this is the series to make CONFIG_COMPAT user-selectable,
        it's been around for a long time but was blocked behind the
        syscall-in-C series.
      
        Plus there's also a few fixes and other minor things.
      
        Summary:
      
         - A fix for a crash in machine check handling on pseries (ie. guests)
      
         - A small series to make it possible to disable CONFIG_COMPAT, and
           turn it off by default for ppc64le where it's not used.
      
         - A few other miscellaneous fixes and small improvements.

      Linus Torvalds authored
      Pull ceph updates from Ilya Dryomov:
       "The main items are:
      
         - support for asynchronous create and unlink (Jeff Layton).
      
           Creates and unlinks are satisfied locally, without waiting for a
           reply from the MDS, provided the client has been granted
           appropriate caps (new in v15.y.z ("Octopus") release). This can be
           a big help for metadata heavy workloads such as tar and rsync.
           Opt-in with the new nowsync mount option.
      
         - multiple blk-mq queues for rbd (Hannes Reinecke and myself).
      
           When the driver was converted to blk-mq, we settled on a single
           blk-mq queue because of a global lock in libceph and some other
           technical debt. These have since been addressed, so allocate a
           queue per CPU to enhance parallelism.
      
         - don't hold onto caps that aren't actually needed (Zheng Yan).
      
           This has been our long-standing behavior, but it causes issues with
           some active/standby applications (synchronous I/O, stalls if the
           standby goes down, etc).
      
         - .snap directory timestamps consistent with ceph-fuse (Luis
           Henriques)"

      Linus Torvalds authored
      Pull libnvdimm and dax updates from Dan Williams:
       "There were multiple touches outside of drivers/nvdimm/ this round to
        add cross arch compatibility to the devm_memremap_pages() interface,
        enhance numa information for persistent memory ranges, and add a
        zero_page_range() dax operation.
      
        This cycle I switched from the patchwork api to Konstantin's b4 script
        for collecting tags (from x86, PowerPC, filesystem, and device-mapper
        folks), and everything looks to have gone ok there. This has all
        appeared in -next with no reported issues.
      
        Summary:
      
         - Add support for region alignment configuration and enforcement to
           fix compatibility across architectures and PowerPC page size
           configurations.
      
         - Introduce 'zero_page_range' as a dax operation. This facilitates
           filesystem-dax operation without a block-device.
      
         - Introduce phys_to_target_node() to facilitate drivers that want to
           know resulting numa node if a given reserved address range was
           onlined.
      
         - Advertise a persistence-domain for of_pmem and papr_scm. The
           persistence domain indicates where cpu-store cycles need to reach
           in the platform-memory subsystem before the platform will consider
           them power-fail protected.
      
         - Promote numa_map_to_online_node() to a cross-kernel generic
           facility.
      
         - Save x86 numa information to allow for node-id lookups for reserved
           memory ranges, deploy that capability for the e820-pmem driver.
      
         - Pick up some miscellaneous minor fixes, that missed v5.6-final,
           including a some smatch reports in the ioctl path and some unit
           test compilation fixups.

      arm64: armv8_deprecated: Fix undef_hook mask for thumb setend · fc226601
      Fredrik Strupe authored
      For thumb instructions, call_undef_hook() in traps.c first reads a u16,
      and if the u16 indicates a T32 instruction (u16 >= 0xe800), a second
      u16 is read, which then makes up the the lower half-word of a T32
      instruction. For T16 instructions, the second u16 is not read,
      which makes the resulting u32 opcode always have the upper half set to
      0.
      
      However, having the upper half of instr_mask in the undef_hook set to 0
      masks out the upper half of all thumb instructions - both T16 and T32.
      This results in trapped T32 instructions with the lower half-word equal
      to the T16 encoding of setend (b650) being matched, even though the upper
      half-word is not 0000 and thus indicates a T32 opcode.
      
      An example of such a T32 instruction is eaa0b650, which should raise a
      SIGILL since T32 instructions with an eaa prefix are unallocated as per
      Arm ARM, but instead works as a SETEND because the second half-word is set
      to b650.
      
      This patch fixes the issue by extending instr_mask to include the
      upper u32 half, which will still match T16 instructions where the upper
      half is 0, but not T32 instructions.

      mm/gup: Mark lock taken only after a successful retake · c7b6a566
      Peter Xu authored
      It's definitely incorrect to mark the lock as taken even if
      down_read_killable() failed.
      
      This wass overlooked when we switched from down_read() to
      down_read_killable() because down_read() won't fail while
      down_read_killable() could.

      mm/mempolicy: Allow lookup_node() to handle fatal signal · ba841078
      Peter Xu authored
      lookup_node() uses gup to pin the page and get node information.  It
      checks against ret>=0 assuming the page will be filled in.  However it's
      also possible that gup will return zero, for example, when the thread is
      quickly killed with a fatal signal.  Teach lookup_node() to gracefully
      return an error -EFAULT if it happens.
      
      Meanwhile, initialize "page" to NULL to avoid potential risk of
      exploiting the pointer.

      platform/chrome: cros_ec_spi: Wait for USECS, not NSECS · a4638771

      The use of `delay_usecs` in terminate_request() was replaced with the new
      `delay` struct used by the SPI subsystem, however the unit was
      set to SPI_DELAY_UNIT_NSECS instead of SPI_DELAY_UNIT_USECS. This fixes that.
