From 4846c5deb9776a7306d0f656ade7505278ac39ba Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Wed, 16 Apr 2008 05:52:26 +1000 Subject: [PATCH] [POWERPC] Clean up some linker and symbol usage * 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.
