Subject: sh: Wire up ARCH_HAS_DEFAULT_IDLE for cpuidle.
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=e869a90ee1235a4f89ecb956e7b7d724d65217c8;p=linux-2.6-omap-h63xx.git

sh: Wire up ARCH_HAS_DEFAULT_IDLE for cpuidle.

cpuidle wants ARCH_HAS_DEFAULT_IDLE defined in order to use the
default idle loop. So, make it accessible and enable it for all
sh machines.
