From: Ma Wupeng <mawupeng1@xxxxxxxxxx>

Commit b05b9f5f9dcf ("x86, mirror: x86 enabling - find mirrored memory ranges")
introduced mirrored memory support for x86. This support rely on UEFI to
report mirrored memory address ranges.  See UEFI 2.5 spec pages 157-158:

  http://www.uefi.org/sites/default/files/resources/UEFI%202_5.pdf

Arm64 can support this too. So mirrored memory support is added to support
arm64.

Patch #1-#2 introduce efi_fake_mem support for arm64.
Patch #3-#4 introduce mirrored memory support form arm64.
Patch #5-#7 fix some bugs for arm64 if memory reliable is enabled.
Patch #8 disable mirror feature if kernelcore is not specified.
Patch #9 remove some redundant code in ia64 efi_init.

Ma Wupeng (9):
  efi: Make efi_print_memmap() public
  arm64: efi: Add fake memory support
  efi: Make efi_find_mirror() public
  arm64/mirror: arm64 enabling - find mirrored memory ranges
  mm: Ratelimited mirrored memory related warning messages
  mm: Demote warning message in vmemmap_verify() to debug level
  mm: Calc the right pfn if page size is not 4K
  efi: Disable mirror feature if kernelcore is not specified
  ia64/efi: Code simplification in efi_init
