From 72099ed2719fc5829bd79c6ca9d1783ed026eb37 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 13 May 2009 22:56:29 +0000 Subject: asm-generic: rename atomic.h to atomic-long.h The existing asm-generic/atomic.h only defines the atomic_long type. This renames it to atomic-long.h so we have a place to add a truly generic atomic.h that can be used on all non-SMP systems.
