      Pull x86 fixes from Thomas Gleixner:
       "The accumulated fixes from this and last week:
      
         - Fix vmalloc TLB flush and map range calculations which lead to
           stale TLBs, spurious faults and other hard to diagnose issues.
      
         - Use fault_in_pages_writable() for prefaulting the user stack in the
           FPU code as it's less fragile than the current solution
      
         - Use the PF_KTHREAD flag when checking for a kernel thread instead
           of current->mm as the latter can give the wrong answer due to
           use_mm()
      
         - Compute the vmemmap size correctly for KASLR and 5-Level paging.
           Otherwise this can end up with a way too small vmemmap area.
      
         - Make KASAN and 5-level paging work again by making sure that all
           invalid bits are masked out when computing the P4D offset. This
           worked before but got broken recently when the LDT remap area was
           moved.
      
         - Prevent a NULL pointer dereference in the resource control code
           which can be triggered with certain mount options when the
           requested resource is not available.
      
         - Enforce ordering of microcode loading vs. perf initialization on
           secondary CPUs. Otherwise perf tries to access a non-existing MSR
           as the boot CPU marked it as available.
      
         - Don't stop the resource control group walk early otherwise the
           control bitmaps are not updated correctly and become inconsistent.
      
         - Unbreak kgdb by returning 0 on success from
           kgdb_arch_set_breakpoint() instead of an error code.
      
         - Add more Icelake CPU model defines so depending changes can be
           queued in other trees"

      Pull timer fixes from Thomas Gleixner:
       "A set of small fixes:
      
         - Repair the ktime_get_coarse() functions so they actually deliver
           what they are supposed to: tick granular time stamps. The current
           code missed to add the accumulated nanoseconds part of the
           timekeeper so the resulting granularity was 1 second.
      
         - Prevent the tracer from infinitely recursing into time getter
           functions in the arm architectured timer by marking these functions
           notrace
      
         - Fix a trivial compiler warning caused by wrong qualifier ordering"

      Pull RAS fixes from Thomas Gleixner:
       "Two small fixes for RAS:
      
         - Use a proper search algorithm to find the correct element in the
           CEC array. The replacement was a better choice than fixing the
           crash causes by the original search function with horrible duct
           tape.
      
         - Move the timer based decay function into thread context so it can
           actually acquire the mutex which protects the CEC array to prevent
           corruption"

      Pull powerpc fixes from Michael Ellerman:
       "One fix for a regression introduced by our 32-bit KASAN support, which
        broke booting on machines with "bootx" early debugging enabled.
      
        A fix for a bug which broke kexec on 32-bit, introduced by changes to
        the 32-bit STRICT_KERNEL_RWX support in v5.1.
      
        Finally two fixes going to stable for our THP split/collapse handling,
        discovered by Nick. The first fixes random crashes and/or corruption
        in guests under sufficient load.
