Merge tag 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost
Pull virtio updates from Michael Tsirkin: "virtio, vhost: new device, fixes, speedups This includes the new virtio crypto device, and fixes all over the place. In particular enabling endian-ness checks for sparse builds found some bugs which this fixes. And it appears that everyone is in agreement that disabling endian-ness sparse checks shouldn't be necessary any longer. So this enables them for everyone, and drops the __CHECK_ENDIAN__ and __bitwise__ APIs. IRQ handling in virtio has been refactored somewhat, the larger switch to IRQ_SHARED will have to wait as it proved too aggressive" * tag 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost: (34 commits) Makefile: drop -D__CHECK_ENDIAN__ from cflags fs/logfs: drop __CHECK_ENDIAN__ Documentation/sparse: drop __CHECK_ENDIAN__ linux: drop __bitwise__ everywhere checkpatch: replace __bitwise__ with __bitwise Documentation/sparse: drop __bitwise__ tools: enable endian checks for all sparse builds linux/types.h: enable endian checks for all sparse builds virtio_mmio: Set dev.release() to avoid warning vhost: remove unused feature bit virtio_ring: fix description of virtqueue_get_buf vhost/scsi: Remove unused but set variable tools/virtio: use {READ,WRITE}_ONCE() in uaccess.h vringh: kill off ACCESS_ONCE() tools/virtio: fix READ_ONCE() crypto: add virtio-crypto driver vhost: cache used event for better performance vsock: lookup and setup guest_cid inside vhost_vsock_lock virtio_pci: split vp_try_to_find_vqs into INTx and MSI-X variants virtio_pci: merge vp_free_vectors into vp_del_vqs ...
