From 2e046b9487dcc60707cac77fb8f744ec830209cd Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Fri, 19 Jun 2009 14:40:51 +0900 Subject: sh: Provide cpu_idle_wait() to fix up cpuidle/SMP build. Crib the x86 cpu_idle_wait() implementation and shove it in with the idle code, subsequently enabling ARCH_HAS_CPU_IDLE_WAIT.

SH7786 is roughly identical to SH-X3 proto SMP, though there are only 2 CPUs. This just wraps in to the existing SH-X3 SMP code with some minor changes for SH7786, including wiring up the IPIs properly, enabling IRQ_PER_CPU, and so forth.
