[PATCH 2/6] 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... 13 Apr 2010 11:41

DMAENGINE: Support for ST-Ericssons DMA40 block v3
2010/3/30 Linus Walleij <linus.walleij(a)stericsson.com>: This is a straightforward driver for the ST-Ericsson DMA40 DMA controller found in U8500, implemented akin to the existing COH 901 318 driver. Dan, if this driver is fine can it be put into the async_tx tree? Andrew already has it in his tree but it... 13 Apr 2010 11:41

[PATCH 6/6] Add comment in alloc_pages_exact_node
alloc_pages_exact_node naming makes some people misleading. They considered it following as. "This function will allocate pages from node which I wanted exactly". But it can allocate pages from fallback list if page allocator can't find free page from node user wanted. So let's comment this NOTE. Actually I ... 13 Apr 2010 11:41

[PATCH 5/6] change alloc function in __vmalloc_area_node
__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.

[PATCH 4/6] change alloc function in vmemmap_alloc_block
