Subject: sparc64: Fix cpufreq notifier registry.
X-Git-Tag: v2.6.26.1~31
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=548da331d07cc879c529b11f82ecd6d4efea5e73;p=platform%2Fkernel%2Flinux-stable.git

sparc64: Fix cpufreq notifier registry.

[ Upstream commit 7ae93f51d7fa8b9130d47e0b7d17979a165c5bc3 ]

Based upon a report by Daniel Smolik.

We do it too early, which triggers a BUG in
cpufreq_register_notifier().
