[PATCH 3/3] x86, mirror: x86 enabling - find mirrored memory ranges

2015-05-04 Thread Tony Luck
UEFI GetMemoryMap() uses a new attribute bit to mark mirrored memory address ranges. See UEFI 2.5 spec pages 157-158: http://www.uefi.org/sites/default/files/resources/UEFI%202_5.pdf On EFI enabled systems scan the memory map and tell memblock about any mirrored ranges. Signed-off-by: Tony Luc
