See http://www.infradead.org/rpr.html Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org This series adds support for automatic interrupt assignment to devices that have a few vectors that are set aside for admin or config purposes and thus should not fall into the general per-cpu assginment pool. The first patch adds that support to the core IRQ and PCI/msi code, and the second is a small tweak to a block layer helper to make use of it. I'd love to have both go into the same tree so that consumers of this (e.g. the virtio, scsi and rdma trees) only need to pull in one of these trees as dependency. Changes since V1: - split up into more patches (thanks to Thomas for the initial work) - simplify internal parameter passing a bit (also thanks to Thomas)
