From 64b9ca9d4eb5eccdea86d967220c67b503a4519b Mon Sep 17 00:00:00 2001 From: Julius Werner Date: Thu, 12 Dec 2013 20:24:48 -0800 Subject: arm: Move libgcc assembly macros to arch/asm.h libgcc/macros.h contains some useful assembly macros that are common in Linux kernel code and facilitate things such as unified ARM/THUMB assembly. This patch moves it to a more general place where it can be used by other code as well.
