"physical_mask" is defined as __PHYSICAL_MASK in page_types.h. MM code seems to use __PHYSICAL_MASK for common usage. But for our use case, if it makes it more readable, I am fine with using "physical_mask".
arch/x86/include/asm/page_types.h:57:#define __PHYSICAL_MASK physical_mask arch/x86/mm/pat/memtype.c:560: return address & __PHYSICAL_MASK;
