From 9ca03a21e320a6bf44559323527aba704bcc8772 Mon Sep 17 00:00:00 2001 From: Russell King Date: Mon, 26 Jul 2010 12:22:12 +0100 Subject: ARM: Factor out common code from cpu_proc_fin() All implementations of cpu_proc_fin() start by disabling interrupts and then flush caches. Rather than have every processors proc_fin() implementation do this, move it out into generic code - and move the cache flush past setup_mm_for_reboot() (so it can benefit from having caches still enabled.) This allows cpu_proc_fin() to become independent of the L1/L2 cache types, and eventually move the L2 cache flushing into the L2 support code.
