page.h uses '_AC' in the definition of PAGE_SIZE, but doesn't include
linux/const.h where this is defined. This produces build warnings when only
asm/page.h is included by asm code.

Not sure why this appears multiple times.

This is sensible even in isolation, so FWIW:

Acked-by: Mark Rutland <mark.rutland@arm.com>

I note that for the !__ASSEMBLY__ portion we use current,
READ_IMPLIES_EXEC, and some VM_* flags, without including the headers
those are defined in. It might be worth fixing those up also.

Mark.
