agp: uninorth: make two functions static

2018-05-10T01:26:08+00:00

Both ‘uninorth_remove_memory’ and ‘null_cache_flush’ can be made static. So make them. Silence the following gcc warning (W=1): drivers/char/agp/uninorth-agp.c:198:5: warning: no previous prototype for ‘uninorth_remove_memory’ [-Wmissing-prototypes] and drivers/char/agp/uninorth-agp.c:473:6: warning: no previous prototype for ‘null_cache_flush’ [-Wmissing-prototypes] Signed-off-by: Mathieu Malaterre Signed-off-by: Dave Airlie

Pull virtio fixups from Michael Tsirkin: - Latest header update will break QEMU (if it's rebuilt with the new header) - and it seems that the code there is so fragile that any change in this header will break it. Add a better interface so users do not need to change their code every time that header changes. - Fix virtio console for spec compliance. * tag 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost: virtio_console: reset on out of memory virtio_console: move removal code virtio_console: drop custom control queue cleanup virtio_console: free buffers after reset virtio: add ability to iterate over vqs virtio_console: don't tie bufs to a vq virtio_balloon: add array of stat names

virtio_console: reset on out of memory

2018-04-25T17:41:29+00:00

When out of memory and we can't add ctrl vq buffers, probe fails. Unfortunately the error handling is out of spec: it calls del_vqs without bothering to reset the device first. To fix, call the full cleanup function in this case. Cc: stable@vger.kernel.org Signed-off-by: Michael S. Tsirkin

virtio_console: move removal code

2018-04-25T17:41:26+00:00

Will make it reusable for error handling. Cc: stable@vger.kernel.org Signed-off-by: Michael S. Tsirkin

virtio_console: drop custom control queue cleanup

2018-04-25T17:41:23+00:00

We now cleanup all VQs on device removal - no need to handle the control VQ specially. Cc: stable@vger.kernel.org Signed-off-by: Michael S. Tsirkin

virtio_console: free buffers after reset

2018-04-25T17:41:16+00:00

Console driver is out of spec. The spec says: A driver MUST NOT decrement the available idx on a live virtqueue (ie. there is no way to “unexpose” buffers). and it does exactly that by trying to detach unused buffers without doing a device reset first. Defer detaching the buffers until device unplug. Of course this means we might get an interrupt for a vq without an attached port now. Handle that by discarding the consumed buffer.

virtio_console: don't tie bufs to a vq

2018-04-25T17:33:13+00:00

an allocated buffer doesn't need to be tied to a vq - only vq->vdev is ever used. Pass the function the just what it needs - the vdev. Cc: stable@vger.kernel.org Signed-off-by: Michael S. Tsirkin

random: fix possible sleeping allocation from irq context

2018-04-24T16:00:08+00:00

We can do a sleeping allocation from an irq context when CONFIG_NUMA is enabled. Fix this by initializing the NUMA crng instances in a workqueue.
