Hi Linus, The following changes since commit a25f0944ba9b1d8a6813fd6f1a86f1bd59ac25a6: Linux 4.9-rc5 (2016-11-13 10:32:32 -0800) are available in the git repository at: git://github.com/awilliam/linux-vfio.git tags/vfio-v4.10-rc1 for you to fetch changes up to 2b8bb1d771f736b8b34bf160115aee1b12d29f83: vfio iommu type1: Fix size argument to vfio_find_dma() in pin_pages/unpin_pages (2016-12-06 12:35:53 -0700) ---------------------------------------------------------------- VFIO updates for v4.10-rc1 - VFIO updates for v4.10 primarily include a new Mediated Device interface, which essentially allows software defined devices to be exposed to users through VFIO. The host vendor driver providing this virtual device polices, or mediates user access to the device. These devices often incorporate portions of real devices, for instance the primary initial users of this interface expose vGPUs which allow the user to map mediated devices, or mdevs, to a portion of a physical GPU. QEMU composes these mdevs into PCI representations using the existing VFIO user API. This enables both Intel KVM-GT support, which is also expected to arrive into Linux mainline during the v4.10 merge window, as well as NVIDIA vGPU, and also Channel I/O devices (aka CCW devices) for s390 virtualization support.

Depending on the ordering of merges versus akpm's branches, a fixup may be necessary as Stephen has provided in linux-next 20161209 as: commit 53fa4eed56cb11d8cea7e15a299cd1054ddc0425 Author: Stephen Rothwell <sfr@canb.auug.org.au> Date: Wed Dec 7 11:02:15 2016 +1100 vfio iommu type1: merge fix for get_user_pages_remote API change Link: http://lkml.kernel.org/r/20161122210511.024ec341@canb.auug.org.au Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Cc: Lorenzo Stoakes <lstoakes@gmail.com> Cc: Michal Hocko <mhocko@suse.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> I'm not sure how these are typically handled, but I'm hoping to queue these changes towards the front of the merge window to allow Intel to get in their dependent changes. No merge issues vs current mainline as of v4.9-rc8+ (a37102dcd7ec).
