Subject: [PATCH 0/2] Backport IBPB on context switch to non-dumpable process
Date: Fri, 2 Mar 2018 13:32:08 -0800 [thread overview]
Message-ID: <cover.1520026221.git.tim.c.chen@linux.intel.com> (raw)
Greg,
I will like to propose backporting "x86/speculation: Use Indirect Branch
Prediction Barrier on context switch" from commit 18bf3c3e in upstream
to 4.9 and 4.4 stable. The patch has already been ported to 4.14 and
4.15 stable. The patch needs mm context id that Andy added in commit
f39681ed. I have lifted the mm context id change from Andy's upstream
patch and included it here.
Thanks.
Tim
