Subject: ARM: add cpu_idle_wait() to support CPUidle on SMP systems.
X-Git-Url: https://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=24e42c9dc74ef38e472bf5b4ee86432e3eee21cf;p=pandora-kernel.git

ARM: add cpu_idle_wait() to support CPUidle on SMP systems.

In order for CPUidle to work on SMP systems, an implementation of
cpu_idle_wait() is needed.

This patch duplicates the x86 implementation of cpu_idle_wait() for
ARM.
