[Crash-utility] [PATCH 1/5] defs.h: Fix the PHYSICAL_PAGE_MASK macro
Original crash defines the PHYSICAL_PAGE_MASK as
(~(PAGE_SIZE-1) & (__PHYSICAL_MASK << PAGE_SHIFT))
It moves left PAGE_SHIFT bits for safety, But As crash expands the physical
bits to 52, this will cause the conversion of phythcal address to virtual
address failed.
Remove the PAGE_SHIFT to fix this problem.

Hi Dave,
The changelog may be not correct, I am not sure why does it move left
PAGE_SHIFT bits. Could you tell me the reason?
