Subject: intel_idle: remove stop/start critical timings
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=94b4624986071a875871378f2a84e3f816764372;p=linux-beck.git

intel_idle: remove stop/start critical timings

The start/stop_critical_timings are called from arch/x86/kernel/process.c
in the cpu_idle loop function.

Remove the ones in the cpuidle driver.
