Pull arm64 fixes from Catalin Marinas:

 - Build fix when !CONFIG_UID16 (the patch is touching generic files but
   it only affects arm64 builds; submitted by Arnd Bergmann)

 - EFI fixes to deal with early_memremap() returning NULL and correctly
   mapping run-time regions

 - Fix CPUID register extraction of unsigned fields (not to be

 - ASID allocator fix to deal with long-running tasks over multiple
   generation roll-overs

 - Revert support for marking page ranges as contiguous PTEs (it leads
   to TLB conflicts and requires additional non-trivial kernel changes)

 - Proper early_alloc() failure check

 - Disable KASan for 48-bit VA and 16KB page configuration (the pgd is
   larger than the KASan shadow memory)

 - Update the fault_info table (original descriptions based on early
   engineering spec)
