cpumask: Cleanup more uses of CPU_MASK and NODE_MASK
* Replace usages of CPU_MASK_NONE, CPU_MASK_ALL, NODE_MASK_NONE, NODE_MASK_ALL to reduce stack requirements for large NR_CPUS and MAXNODES counts. * In some cases, the cpumask variable was initialized but then overwritten with another value. This is the case for changes like this: - cpumask_t oldmask = CPU_MASK_ALL; + cpumask_t oldmask; Signed-off-by: Mike Travis <travis@sgi.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
