From mboxrd@z Thu Jan 1 00:00:00 1970 From: Peter Zijlstra Subject: [PATCH 00/17] mm: mmu_gather rework Date: Thu, 17 Feb 2011 17:23:27 +0100 Message-ID: <20110217162327.434629380@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 patch is a fix to the tile architecture, the subsequent 9 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. Finally there are 4 patches that convert various architectures over to asm-generic/tlb.h, these are compile tested only and basically RFC. After this only um and s390 are left -- um should be straight forward, s390 wants a bit more, but more on that in another email. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
