From mboxrd@z Thu Jan 1 00:00:00 1970 From: Nicholas Piggin Subject: [PATCH 0/3] mm: dirty/accessed pte optimisations Date: Tue, 28 Aug 2018 21:20:31 +1000 Message-ID: <20180828112034.30875-1-npiggin@gmail.com> Return-path: Sender: linux-kernel-owner@vger.kernel.org To: linux-mm@kvack.org Cc: Nicholas Piggin , linux-arch@vger.kernel.org, linux-kernel@vger.kernel.org, linuxppc-dev@lists.ozlabs.org, Andrew Morton , Linus Torvalds List-Id: linux-arch.vger.kernel.org Here are some patches that didn't get much comment last time. It looks like x86 might benefit too though, so that might get people interested. I improved changelogs and added some comments, but no real logic changes. I hope I didn't get the x86 numbers wrong, they're more significant than I expected so it could quite well be a problem with my test (corrections welcome). Any data from other archs would be interesting too. Andrew perhaps if there aren't objections these could go in mm for a while.
