Matt Fleming 0b184a30d0 ia64: Reduce stack usage by iterating over nodemask ... GCC complains about sn2_global_tlb_purge() because of the large stack required by the function, arch/ia64/sn/kernel/sn2/sn2_smp.c: In function 'sn2_global_tlb_purge': arch/ia64/sn/kernel/sn2/sn2_smp.c:319:1: warning: the frame size of 2176 bytes is larger than 2048 bytes [-Wframe-larger-than=] 2048 bytes of the stack are consumed by the node ID array 'nasids[]'. But we don't actually need to put the ID array on the stack and can use nodemask operations.
