We steal the _PAGE_COHERENCE bit and use that for indicating _PAGE_NUMA. We clear the _PAGE_PRESENT bit and also invalidate the hpte entry on setting _PAGE_NUMA. The next fault on that page will be considered a numa fault. Changes from V1: * Dropped few patches related pmd update because batch handling of pmd pages got dropped from core code 0f19c17929c952c6f0966d93ab05558e7bf814cc "mm: numa: Do not batch handle PMD pages" This also avoided the large lock contention on page_table_lock that we observed with the previous series. -aneesh -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
