Message-ID: <cover.1324484752.git.mst@redhat.com> Date: Wed, 21 Dec 2011 18:29:05 +0200 From: "Michael S. Tsirkin" <mst@...hat.com> To: linux-alpha@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCHv2 RFC (repost) 00/16] pci: use generic pci_iomap on all architectures This reposting combines the latest version of the patches. As this is just a repost, separate versions was already sent to maintainers, I cut down the To list to just lkml and linux-arch. This patchset has been on linux-next for several weeks now. I intend to send pull request to Linus come 3.3 merge window: They touch a lot of arches and have interdependencies, so merging separately seems to make sense. As Jesse Barnes noted: the PCI changes look nice (pulling all that duplicated code out looks good), though it would be good to get a few more arch maintainer acks/tested-bys for this. The patchset is available from my tree: git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost.git linux-next or from linux-next. Many architectures don't want to pull in iomap.c, so they ended up duplicating pci_iomap from that file. That function isn't trivial, and we are going to modify it https://lkml.org/lkml/2011/11/14/183 so the duplication hurts. This reduces the scope of the problem significantly, by moving pci_iomap to a separate file and referencing that from all architectures. Tested on x86, build tested on alpha, mips64 and powerpc64. -- 1.7.5.53.gc233e Michael S.
