Peter Anvin <hpa@xxxxxxxxx> Peter, Yinghi - i zapped this and the other e820 patch from x86/urgent as Linus already applied slightly different versions upstream: 7c5371c: x86: add boundary check for 32bit res before expand e820 resource to alignment 4364467: x86: fix power-of-2 round_up/round_down macros Mind checking what the differences are and queue up any deltas that might still be needed?
