This patch includes page.h header into linker scripts that allow us to use PAGE_SIZE macro instead of numeric constant. To be able to include page.h into linker scripts page.h is needed for some modification - i.e. we need to use __ASSEMBLY__ and _AC macro [jdike@linux.intel.com - fixed conflict with as-layout.h] Signed-off-by: Cyrill Gorcunov <gorcunov@gmail.com> Signed-off-by: Jeff Dike <jdike@linux.intel.com> Cc: WANG Cong <xiyou.wangcong@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
