Subject[patch 07/19] UML - Stop using libc asm/page.h
-stable review patch.  If anyone has any objections, please let us know.

------------------
From: Jeff Dike <jdike@addtoit.com>
commit 71f926f2ea61994470a53c9e11d3ef993197cada in mainline.

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.

[ jdike - added arch/um/kernel/skas/clone.c for -stable ]
