Message-ID: <20070714205709.GA9478@aepfle.de>
Date: Sat, 14 Jul 2007 22:57:09 +0200
From: Olaf Hering <olaf@...fle.de>
To: Andrew Morton <akpm@...ux-foundation.org>,
linux-kernel@...r.kernel.org
Subject: [PATCH] remove PAGE_SIZE from headers_install
Declare PAGE_SIZE as getpagesize() for userspace.
PAGE_SIZE is used in resource.h and shm.h
define PAGE_SIZE in asm-generic/page.h
guard get_order() with _ARCH_HAS_GET_ORDER for ia64 and xtensa
include asm-generic/page.h in asm/page.h
make asm/page.h nearly empty by moving the #ifdef guards up
remove unneeded page.h export from frv
Signed-off-by: Olaf Hering <olaf@...fle.de>
