From mboxrd@z Thu Jan 1 00:00:00 1970 From: Peter Zijlstra Subject: [PATCH 00/13] mm: mmu_gather rework -v2 Date: Wed, 02 Mar 2011 18:50:04 +0100 Message-ID: <20110302175004.222724818@chello.nl> Return-path: Sender: owner-linux-mm@kvack.org To: Andrea Arcangeli , Avi Kivity , Thomas Gleixner , Rik van Riel , Ingo Molnar , akpm@linux-fo Cc: linux-kernel@vger.kernel.org, linux-arch@vger.kernel.org, linux-mm@kvack.org, Benjamin Herrenschmidt , David Miller , Hugh Dickins , Mel Gorman , Nick Piggin , Peter Zijlstra , Paul McKenney , Yanmin Zhang List-Id: linux-arch.vger.kernel.org Rework the existing mmu_gather infrastructure. The direct purpose of these patches was to allow preemptible mmu_gather, but even without that I think these patches provide an improvement to the status quo. The first 10 patches rework the mmu_gather infrastructure. For review purpose I've split them into generic and per-arch patches with the last of those a generic cleanup. For the final commit I would provide a roll-up of these patches so as not to wreck bisectability of non generic archs. The next patch provides generic RCU page-table freeing, and the follow up is a patch converting s390 to use this. I've also got 4 patches from DaveM lined up (not included in this series) that uses this to implement gup_fast() for sparc64. Then there is one patch that extends the generic mmu_gather batching. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
