      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"
