Prev: [PATCH 4/4] crypto: pcrypt - Dont calulate a callback cpu on empty callback cpumask
Next: [PATCH 0/3] MAX8998 changes for RTC
From: Steffen Klassert on 20 Jul 2010 02:50
The counting of the cpu index got lost with a recent commit.
This patch restores it. This fixes a hang of the parallel worker
threads on cpu hotplug.
