From a9079ca0cb15feda15e7a380092e02d5cd834148 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Wed, 21 Apr 2010 12:01:06 +0900 Subject: sh: Tidy CPU probing and fixup section annotations. This does a detect_cpu_and_cache_system() -> cpu_probe() rename, tidies up the unused return value, and stuffs it under __cpuinit in preparation for CPU hotplug.
