    cpumask: reduce stack usage in SD_x_INIT initializers · 7c16ec58
    Mike Travis authored
      * Remove empty cpumask_t (and all non-zero/non-null) variables
        in SD_*_INIT macros.  Use memset(0) to clear.  Also, don't
        inline the initializer functions to save on stack space in
        build_sched_domains().
    
      * Merge change to include/linux/topology.h that uses the new
        node_to_cpumask_ptr function in the nr_cpus_node macro into
        this patch.
    
    Depends on:
    	[mm-patch]: asm-generic-add-node_to_cpumask_ptr-macro.patch
    	[sched-devel]: sched: add new set_cpus_allowed_ptr function
