During testing 32bit numa unifying code from tj, found one system with more than 64g fails to use numa. It turns out we do not trim numa meminfo correctly against max_pfn in case start address of a node is higher than 64GiB. Bug fix made it to tip tree. This patch moves the checking and trimming to a separate loop. So we don't need to compare low/high in following merge loops. It makes the code more readable. Also it makes the node merge printouts less strange. On a 512GiB numa system with 32bit, before: > NUMA: Node 0 [0,a0000) + [100000,80000000) -> [0,80000000) > NUMA: Node 0 [0,80000000) + [100000000,1080000000) -> [0,1000000000) after: > NUMA: Node 0 [0,a0000) + [100000,80000000) -> [0,80000000) > NUMA: Node 0 [0,80000000) + [100000000,1000000000) -> [0,1000000000) Signed-off-by: Yinghai Lu <yinghai@kernel.org> [Updated patch description and comment slightly.] Signed-off-by: Tejun Heo <tj@kernel.org> |
