Subject: [PATCH] APM: Remove redundant call to set_cpus_allowed
X-Git-Tag: v2.6.13-rc4~44
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=910de55c6653d76f90380c80f0b7a395f12019e3;p=profile%2Fivi%2Fkernel-x86-ivi.git

[PATCH] APM: Remove redundant call to set_cpus_allowed

machine_power_off now always switches to the boot cpu so there
is no reason for APM to also do that.
