Subject: [PATCH 0/8] THP fixes for ppc64
Date: Tue, 29 Jul 2014 15:07:41 +0530 [thread overview]
Message-ID: <1406626669-31154-1-git-send-email-aneesh.kumar@linux.vnet.ibm.com> (raw)
Hi,
This patch series fixes machine check exception that we observed when using
transparent huge page along with 4k hash pte on power bare metal platform.
Patch "powerpc: mm: Use read barrier when creating real_pte" is not really
related to thp, but was added in the series because it is fixing a related
issue with 4k pte. That patch was not really needed to fix the MCE.
Aneesh Kumar K.V (8):
powerpc: thp: Add write barrier after updating the valid bit
powerpc: thp: don't recompute vsid and ssize in loop on invalidate
powerpc: thp: invalidate old 64K based hash page mapping before insert
of 4k pte
powerpc: thp: Handle combo pages in invalidate
powerpc: thp: inalidate with vpn in loop
powerpc: thp: use ACCESS_ONCE when loading pmdp
powerpc: mm: Use read barrier when creating real_pte
powerpc: thp: Add tracepoints to track hugepage invalidate
