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.
