We used to fail the set_vq_state() since it was not supported yet by
the virtio spec. But if the bus tries to set the state which is equal
to the device initial state after reset, we can let it go.
This is a must for virtio_vdpa() to set vq state during probe which is
required for some vDPA parents.

This patch extends the vdpa_vq_state to support packed virtqueue
state which is basically the device/driver ring wrap counters and the
avail and used index. This will be used for the virito-vdpa support
for the packed virtqueue and the future vhost/vhost-vdpa support for
the packed virtqueue.

For split virtqueue, we used to depend on the address, length and
flags stored in the descriptor ring for DMA unmapping. This is unsafe
for the case since the device can manipulate the behavior of virtio
driver, IOMMU drivers and swiotlb.
For safety, maintain the DMA address, DMA length, descriptor flags and
next filed of the non indirect descriptors in vring_desc_state_extra
when DMA API is used for virtio as we did for packed virtqueue and use
those metadata for performing DMA operations. Indirect descriptors
should be safe since they are using streaming mappings.
With this the descriptor ring is write only form the view of the
driver.
This slight increase the footprint of the drive but it's not noticed
through pktgen (64B) test and netperf test in the case of virtio-net.

We should not depend on the DMA address, length and flag of descriptor
table since they could be wrote with arbitrary value by the device. So
this patch switches to use the stored one in desc_extra.
Note that the indirect descriptors are fine since they are read-only
streaming mappings.

After device reset, the virtqueues are not ready so clear the ready
field.
Failing to do so can result in virtio_vdpa failing to load if the device
was previously used by vhost_vdpa and the old values are ready.
virtio_vdpa expects to find VQs in "not ready" state.

There are currently two cases where we poll TX vq not in response to a
callback: start xmit and rx napi. We currently do this with callbacks
enabled which can cause extra interrupts from the card. Used not to be
a big issue as we run with interrupts disabled but that is no longer the
case, and in some cases the rate of spurious interrupts is so high
linux detects this and actually kills the interrupt.
Fix up by disabling the callbacks before polling the tx vq.

Notice that this seems to be a Duff device for performance[1]. So,
although the code looks a bit _funny_, I didn't want to refactor
or modify it beyond merely adding a fallthrough marking, which
might be the least disruptive way to fix this issue.

The code in xcs_resume() probably didn't work as intended. It uses
struct drm_device.irq, which is allocated to 0, but never initialized
by i915 to the device's interrupt number.
Change all calls to synchronize_hardirq() to intel_synchronize_irq(),
which uses the correct interrupt. _hardirq() functions are not needed
in this context.
v5:
* go back to _hardirq() after PCI probe reported wrong
context; add rsp comment
v4:

intel_dp_vsc_sdp_unpack() was using a memset() size (36, struct dp_sdp)
larger than the destination (24, struct drm_dp_vsc_sdp), clobbering
fields in struct intel_crtc_state after infoframes.vsc. Use the actual
target size for the memset().

Pull ARM development updates from Russell King:
- Make it clear __swp_entry_to_pte() uses PTE_TYPE_FAULT
- Updates for setting vmalloc size via command line to resolve an issue
with the 8MiB hole not properly being accounted for, and clean up the
code.
- ftrace support for module PLTs
- Spelling fixes
- kbuild updates for removing generated files and pattern rules for
generating files
- Clang/llvm updates
- Change the way the kernel is mapped, placing it in vmalloc space
instead.
- Remove arm_pm_restart from arm and aarch64.
