      Pull block fixes from Jens Axboe:
       "Final round of fixes for this merge window - some of this has come up
        after the initial pull request, and some of it was put in a post-merge
        branch before the merge window.
      
        This contains:
      
         - Fix for a bad check for an error on dma mapping in the mtip32xx
           driver, from Alexey Khoroshilov.
      
         - A set of fixes for lightnvm, from Javier, Matias, and Wenwei.
      
         - An NVMe completion record corruption fix from Marta, ensuring that
           we read things in the right order.
      
         - Two writeback fixes from Tejun, marked for stable@ as well.
      
         - A blk-mq sw queue iterator fix from Thomas, fixing an oops for
           sparse CPU maps.  They hit this in the hot plug/unplug rework"
      
      * 'for-linus' of git://git.kernel.dk/linux-block:
        nvme: avoid cqe corruption when update at the same time as read
        writeback, cgroup: fix use of the wrong bdi_writeback which mismatches the inode
        writeback, cgroup: fix premature wb_put() in locked_inode_to_wb_and_lock_list()
        blk-mq: Use proper cpumask iterator
        mtip32xx: fix checks for dma mapping errors
        lightnvm: do not load L2P table if not supported
        lightnvm: do not reserve lun on l2p loading
        nvme: lightnvm: return ppa completion status
        lightnvm: add a bitmap of luns

           getting support upstream before the product release.  Also two

         - Preempt tracer now shows functions where preemption is disabled but
           interrupts are still enabled.

         - Updates were done to function tracing to allow better performance

      Pull thermal updates from Zhang Rui:
      
       - Fix a regression where bogus trip points on some Lenovo laptops start
         to screw up thermal control after commit 81ad4276 ("Thermal:
         initialize thermal zone device correctly").
      
         On these Lenovo laptops, a bogus passive trip point is reported,
         which is 0 degree Celsius.  Without commit 81ad4276, thermal zone
         fails to set cooling devices to proper cooling state, which is a bug.
         But with commit 81ad4276 applied, the processors are always
         throttled on these Lenovo laptops because the current temperature is
         always higher than the passive trip point.
      
         Fix things to ignore such bogus trip points.  (Zhang Rui)
      
       - Introduce Mediatek thermal driver.  (Sascha Hauer)
      
       - Introduce devm_ versions of OF thermal sensor register API.  (Laxman
         Dewangan)
      
       - Changes in Kconfigs to allow compile test on UM arch.  (Krzysztof

       - Introduce Skylake support in intel_pch_thermal driver.  (Srinivas
         Pandruvada)

      arm64: mm: allow preemption in copy_to_user_page · 691b1e2e
      Mark Rutland authored
      Currently we disable preemption in copy_to_user_page; a behaviour that
      we inherited from the 32-bit arm code. This was necessary for older
      cores without broadcast data cache maintenance, and ensured that cache
      lines were dirtied and cleaned by the same CPU. On these systems dirty
      cache line migration was not possible, so this was sufficient to
      guarantee coherency.
      
      On contemporary systems, cache coherence protocols permit (dirty) cache
      lines to migrate between CPUs as a result of speculation, prefetching,
      and other behaviours. To account for this, in ARMv8 data cache
      maintenance operations are broadcast and affect all data caches in the
      domain associated with the VA (i.e. ISH for kernel and user mappings).
      
      In __switch_to we ensure that tasks can be safely migrated in the middle
      of a maintenance sequence, using a dsb(ish) to ensure prior explicit
      memory accesses are observed and cache maintenance operations are
      completed before a task can be run on another CPU.
      
      Given the above, it is not necessary to disable preemption in
      copy_to_user_page. This patch removes the preempt_{disable,enable}
      calls, permitting preemption.

      arm64: consistently use p?d_set_huge · c661cb1c
      Mark Rutland authored
      Commit 324420bf ("arm64: add support for ioremap() block
      mappings") added new p?d_set_huge functions which do the hard work to
      generate and set a correct block entry.
      
      These differ from open-coded huge page creation in the early page table
      code by explicitly setting the P?D_TYPE_SECT bits (which are implicitly
      retained by mk_sect_prot() for any valid prot), but are otherwise
      identical (and cannot fail on arm64).
      
      For simplicity and consistency, make use of these in the initial page
      table creation code.

      arm64: kaslr: use callee saved register to preserve SCTLR across C call · d5e57437
      Ard Biesheuvel authored
      The KASLR code incorrectly expects the contents of x18 to be preserved
      across a call into C code, and uses it to stash the contents of SCTLR_EL1
      before enabling the MMU. If the MMU needs to be disabled again to create
      the randomized kernel mapping, x18 is written back to SCTLR_EL1, which is
      likely to crash the system if x18 has been clobbered by kasan_early_init()
      or kaslr_early_init(). So use x22 instead, which is not in use so far in
      head.S

      Pull x86 platform driver updates from Darren Hart:
       "Significant refactoring of Dell laptop drivers, modularizing the
        smbios code.  Multiple new platforms added for ideapad, asus, dell,
        and alienware using existing quirks.  A few fixes and cleanups.
      
        hp-wmi:
         - Remove GPS rfkill support via pre-2009 interface

        ideapad-laptop:
         - Add ideapad Y700 (15) to the no_hw_rfkill DMI list
      
        fujitsu-laptop:
         - Support radio toggle button

         - depends DMI
      
        dell-wmi:
         - support Dell Inspiron M5110
         - properly process Dell Instant Launch hotkey

         - Support new hotkeys on the XPS 13 9350 (Skylake)
         - Clean up hotkey table size check
         - Stop storing pointers to DMI tables
      
        dell-laptop:
         - move dell_smi_error() to dell-smbios
         - use dell_smbios_find_token() instead of find_token_location()
         - use dell_smbios_find_token() instead of find_token_id()
         - extract SMBIOS-related code to a separate module
      
        dell-smbios:
         - rename dell_smi_error() to dell_smbios_error()
         - make da_tokens static
         - remove find_token_{id,location}()
         - implement new function for finding DMI table 0xDA tokens
         - make the SMBIOS buffer static
         - return the SMBIOS buffer from dell_smbios_get_buffer()
         - don't return an SMBIOS buffer from dell_smbios_send_request()
         - don't pass an SMBIOS buffer to dell_smbios_send_request()
         - rename dell_send_request() to dell_smbios_send_request()
         - rename release_buffer() to dell_smbios_release_buffer()
         - rename clear_buffer() to dell_smbios_clear_buffer()
         - rename get_buffer() to dell_smbios_get_buffer()
      
        dell-led:
         - use dell_smbios_send_request() for performing SMBIOS calls
         - use dell_smbios_find_token() for finding mic DMI tokens

         - Add a module parameter to disable hotkeys registration
         - Add sysfs entries for the Cooling Method feature
