Bhat Date: Sat, 9 Feb 2013 00:11:29 +0000 (-0800) Subject: rcu: Remove comment referring to __stop_machine() X-Git-Tag: upstream/snapshot3+hdmi~4414^2~88^2~1^2~4 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0bdf5984ad647ba5d1c09ed66a75e5bf609456ba;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git rcu: Remove comment referring to __stop_machine() Although it used to be that CPU_DYING notifiers executed on the outgoing CPU with interrupts disabled and with all other CPUs spinning, this is no longer the case. This commit therefore removes this obsolete comment. Signed-off-by: Srivatsa S. Bhat Signed-off-by: Paul E.
