Subject: [PATCH 08/13] [POWERPC] Clean up some linker and symbol usage
Date: Tue, 15 Apr 2008 14:52:26 -0500 [thread overview]
Message-ID: <1208289151-2925-9-git-send-email-galak@kernel.crashing.org> (raw)
In-Reply-To: <1208289151-2925-8-git-send-email-galak@kernel.crashing.org>
* PAGE_OFFSET is not always the start of code, use _stext instead.
* grab PAGE_SIZE and KERNELBASE from asm/page.h like ppc64 does. Makes the
code a bit more common and provide a single place to manipulate the
defines for things like kdump.
