Subject: MIPS: Idle: Don't call local_irq_disable() in cpu_wait() implementations.
X-Git-Tag: submit/tizen_common/20140905.094502~2852^2~5
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d882f07a83642283b9bc4e7f4c56ac4982c5e629;p=sdk%2Femulator%2Femulator-kernel.git

MIPS: Idle: Don't call local_irq_disable() in cpu_wait() implementations.

The generic idle loop has already disabled interrupts so this is redundant.
