[Crash-utility] [PATCH v3 1/6] 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.
