X-Git-Tag: v2.6.29-rc1~521^2~9
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=263ec6457bb23d57b575ede18ff6c3d11e0b4e96;p=linux-2.6-omap-h63xx.git

cpumask: convert RCU implementations, fix

Impact: cleanup

This warning:

 kernel/rcuclassic.c: In function ‘rcu_start_batch’:
 kernel/rcuclassic.c:397: warning: passing argument 1 of ‘cpumask_andnot’ from incompatible pointer type

triggers because one usage site of rcp->cpumask was not converted
to to_cpumask(rcp->cpumask). There's no ill effects of this bug.
