       "A set of fixes for RAS/MCE:
      
         - Improve the error message when the kernel cannot recover from a MCE
           so the maximum amount of information gets provided.
      
         - Individually check MCE recovery features on SkyLake CPUs instead of
           assuming none when the CAPID0 register does not advertise the
           general ability for recovery.
      
         - Prevent MCE to output inconsistent messages which first show an
           error location and then claim that the source is unknown.
      
         - Prevent overwriting MCi_STATUS in the attempt to gather more
           information when a fatal MCE has alreay been detected. This leads
           to empty status values in the printout and failing to react
           promptly on the fatal event"

      Pull timer fixes from Thomas Gleixner:
       "A small set of fixes for time(r) related issues:
      
         - Fix a long standing conversion issue in jiffies_to_msecs() for odd
           HZ values like 1024 or 1200 which resulted in returning 0 for small
           jiffies values due to rounding down.
      
         - Use the proper CONFIG symbol in the new Y2038 safe compat code for
           posix-timers. Not yet a visible breakage, but this will immediately
           trigger when the architecture support for the new interfaces is
           merged.
      
         - Return an error code in the STM32 clocksource driver on failure
           instead of success.
      
         - Remove the redundant and stale irq disabled check in the posix cpu
           timer code. The check is at the wrong place anyway and lockdep
           already covers it via the sighand lock locking coverage"

      Pull irq fixes from Thomas Gleixner:
       "A set of fixes mostly for the ARM/GIC world:
      
         - Fix the MSI affinity handling in the ls-scfg irq chip driver so it
           updates and uses the effective affinity mask correctly
      
         - Prevent binding LPIs to offline CPUs and respect the Cavium erratum
           which requires that LPIs which belong to an offline NUMA node are
           not bound to a CPU on a different NUMA node.
      
         - Free only the amount of allocated interrupts in the GIC-V2M driver
           instead of trying to free log2(nrirqs).
      
         - Prevent emitting SYNC and VSYNC targetting non existing interrupt
           collections in the GIC-V3 ITS driver
      
         - Ensure that the GIV-V3 interrupt redistributor is correctly
           reprogrammed on CPU hotplug

         - an errata workaround for the BCM5300X platform.

           the fix applying cleanly back as far as v3.17.
      
         - addition of read barriers to in{b,w,l,q}() functions, matching
           behavior of other architectures & mirroring the equivalent addition
           to read{b,w,l,q} in v4.17-rc2.

         and THP on Power9 Radix.
      
       - three fixes to try and make our panic handling more robust by hard
         disabling interrupts, and not marking stopped CPUs as offline because
         they haven't been properly offlined.
      
       - three other minor fixes.
