Subject: [PATCH 1/6] UML - Stop using libc asm/page.h
Remove includes of asm/page.h from libc code. This header seems to be
disappearing, and UML doesn't make much use of it anyway.
The one use, PAGE_SHIFT in stub.h, is handled by copying the constant
from the kernel side of the house in common_offsets.h.
