      Pull HID updates from Jiri Kosina:
      
       - support for U2F Zero device, from Andrej Shadura
      
       - logitech-dj has historically been treating devices behind
         non-unifying receivers as generic devices, using the HID emulation in
         the receiver. That had several shortcomings (special keys handling,
         battery level monitoring, etc). The driver has been reworked to
         enumarate (and directly communicate with) the devices behind the
         receiver, to avoid the (too) generic HID implementation in the
         receiver itself. All the work done by Benjamin Tissoires and Hans de
         Goede.
      
       - restructuring of intel-ish driver in order to allow for multiple
         clients of the ISH implementation, from Srinivas Pandruvada
      
       - several other smaller fixes and assorted device ID additions

       "One small feature was added this release but the bulk of the diffstat

           Wysocki).

           (OPP) framework (Andrew-sh.Cheng).

        MMIO has been performed inside the critical section.

      Pull x86 mm updates from Ingo Molnar:
       "The changes in here are:
      
         - text_poke() fixes and an extensive set of executability lockdowns,
           to (hopefully) eliminate the last residual circumstances under
           which we are using W|X mappings even temporarily on x86 kernels.
           This required a broad range of surgery in text patching facilities,
           module loading, trampoline handling and other bits.
      
         - tweak page fault messages to be more informative and more
           structured.
      
         - remove DISCONTIGMEM support on x86-32 and make SPARSEMEM the
           default.
      
         - reduce KASLR granularity on 5-level paging kernels from 512 GB to
           1 GB.

         - Clean up over a decade worth of cruft accumulated.

        corruption and sporadic failures much later on"
