Eric Dumazet 529a340402 [PATCH] x86_64: Optimize NUMA node hash function ... Compute the highest possible value for memnode_shift, in order to reduce footprint of memnodemap[] to the minimum, thus making all users (phys_to_nid(), kfree()), more cache friendly. Before the patch : Node 0 MemBase 0000000000000000 Limit 00000001ffffffff Node 1 MemBase 0000000200000000 Limit 00000003ffffffff Using 23 for the hash shift. Max adder is 3ffffffff After the patch : Node 0 MemBase 0000000000000000 Limit 00000001ffffffff Node 1 MemBase 0000000200000000 Limit 00000003ffffffff Using 33 for the hash shift. In this case, only 2 bytes of memnodemap[] are used, instead of 2048 Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>		2005-11-14 19:55:15 -08:00
