This patchset converts cpuset to use new cpumask API, and thus remove on stack cpumask_t to reduce stack usage.
Before: # cat kernel/cpuset.c include/linux/cpuset.h | grep -c cpumask_t 21 After: # cat kernel/cpuset.c include/linux/cpuset.h | grep -c cpumask_t 0
The patchset is based on mmotm 2008-12-30-16-05.
