How much did you test sparsemem on x86-64 NUMA ? There are various cases that probably need to be checked, AMD with SRAT, AMD without SRAT, AMD with more than 4GB RAM, Summit(?), NUMA EMULATION etc. If all that works I would have no problem with removing the old code. -Andi -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
