powerpc/cell: Use vzalloc rather than vmalloc and memset in spu_alloc_lscsa_std
Hi, We can get rid of a memset in arch/powerpc/platforms/cell/spufs/lscsa_alloc.c::spu_alloc_lscsa_std() by using vzalloc() rather than vmalloc()+memset(). Completely untested patch below since I have no hardware nor tools to compile this. Signed-off-by: Jesper Juhl <jj@chaosbits.net> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
