Merge tag 'efi-next-for-v7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi

Pull EFI updates from Ard Biesheuvel:
 "Again not a busy cycle for EFI, just some minor tweaks and bug fixes:

   - Enable boot graphics resource table (BGRT) on Xen/x86

   - Correct a misguided assumption in the memory attributes table
     sanity check

   - Start tagging efi_mem_reserve()'d regions as MEMBLOCK_RSRV_KERN

   - Some other minor fixes and cleanups"

* tag 'efi-next-for-v7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi:
  efi/capsule-loader: fix incorrect sizeof in phys array reallocation
  efi: Tag memblock reservations of boot services regions as RSRV_KERN
  memblock: Permit existing reserved regions to be marked RSRV_KERN
  efi/memattr: Fix thinko in table size sanity check
  efi: libstub: fix type of fdt 32 and 64bit variables
  efi: Drop unused efi_range_is_wc() function
  efi: Enable BGRT loading under Xen
