Hi Linus,
This is a fix for a discard performance issues on a particular NVMe
device. I originally thought this regression was introduced prior to
this merge window and wanted to just make it part of the 4.4 merge
window patches and mark it stable, but it has in fact been introduced in
this series

At present scheduler resets task's wait start timestamp when the task
migrates to another rq. This misleads scheduler itself into reporting
less wait time than actual by omitting time spent for waiting prior to
migration and also more wait count than actual by counting migration as
wait end event

If no primary handler is specified then a default one is assigned which
always returns IRQ_WAKE_THREAD. This handler requires the IRQF_ONESHOT,
because the source of interrupt is not disabled.

This switches virtio to use the DMA API unconditionally. I'm sure
it breaks things, but it seems to work on x86 using virtio-pci, with

legacy variant.

- Fix a D

This fixes virtio-pci on platforms and busses that have IOMMUs. This
will break the experimental QEMU Q35 IOMMU support until QEMU is
fixed. In exchange, it fixes physical virtio hardware as well as

We should clean up the virtqueue API to do
virtio_ring currently sends the device (usually a hypervisor)

From: Andy Lutomirski
Once virtio starts using the DMA API, we won't be able to safely DMA
from the stack. virtio-net does a couple of config DMA requests
from small stack buffers -- switch to using dynamically-allocated
memory.
This should have no effect on any performance-critical code paths.
