[PATCH v2] change alloc function in __vmalloc_area_node
V2 * Add some reviewed-by __vmalloc_area_node never pass -1 to alloc_pages_node. It means node's validity check is unnecessary. So we can use alloc_pages_exact_node instead of alloc_pages_node. It could avoid comparison and branch as 6484eb3e2a81807722 tried. Cc: Nick Piggin <npiggin(a)suse.de> Reviewed-by: Me... 14 Apr 2010 12:09

[PATCH] change alloc function in pcpu_alloc_pages
alloc_pages_node is called with cpu_to_node(cpu). I think cpu_to_node(cpu) never returns -1. (But I am not sure we need double check.) So we can use alloc_pages_exact_node instead of alloc_pages_node. It could avoid comparison and branch as 6484eb3e2a81807722 tried. Cc: Tejun Heo <tj(a)kernel.org> Cc: Christoph... 14 Apr 2010 12:09
