From 7bf04be8f48ceeeffa5b5a79734d6d6e0d59e5f8 Mon Sep 17 00:00:00 2001 From: Stratos Psomadakis Date: Fri, 25 Feb 2011 22:46:13 +0200 Subject: x86, asm: Cleanup unnecssary macros in asm-offsets.c PAGE_SIZE_asm, PAGE_SHIFT_asm, THREAD_SIZE_asm can be safely removed from asm-offsets.c, and be replaced by their non-'_asm' counterparts in the code that uses them, since the _AC macro defined in include/linux/const.h makes PAGE_SIZE/PAGE_SHIFT/THREAD_SIZE work with as.
