Subject: [PATCH -V2 0/5] powerpc: mm: Numa faults support for ppc64
Date: Mon, 18 Nov 2013 14:58:08 +0530 [thread overview]
Message-ID: <1384766893-10189-1-git-send-email-aneesh.kumar@linux.vnet.ibm.com> (raw)
Hi,
This patch series add support for numa faults on ppc64 architecture. 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.
