[PATCH 0/2] virtio: Replace CONFIG_PM with CONFIG_PM_SLEEP
This patchset replace CONFIG_PM with CONFIG_PM_SLEEP for all virtio
drivers and virtio pci driver.
With patch 1/2, two compile warnings are eliminated for virtio pci
driver, and patch 2/2 is a clean up for all virtio drivers as suggested
by Amit Shah.

[PATCH] virtio_pci: pm: Use CONFIG_PM_SLEEP instead of CONFIG_PM
The virtio_pci_freeze/restore are defined under CONFIG_PM but is used
by SET_SYSTEM_SLEEP_PM_OPS macro, which is defined under
CONFIG_PM_SLEEP. So if CONFIG_PM_SLEEP is not cofigured but
CONFIG_PM_RUNTIME is, the following warning message appeared:

Unless I'm missing something, we only build any of the restore code
(including the write_cr8() call) if CONFIG_PM_SLEEP is set, and that
selects CONFIG_PM, so we should be fine, I think.

[RFC PATCH 0/8] virtio: Support for hibernation (S4)
Hello,
These patches are an initial attempt at supporting hibernation for
virtio drivers.
The default configuration of event_index=on doesn't work; i.e. restore
from a hibernated image only works if the devices have event_index
support turned off. I have not yet dug into this, but is most likely
due to some state not being sync'ed. This could be related to the
hack that is patch 3.

[PATCH v3 00/11] virtio: S4 support
Hi,
These patches add support for S4 to virtio (pci) and all drivers.
For each driver, all vqs are removed before hibernation, and then
re-created after restore. Some driver-specific uninit and init work
is also done in the freeze and restore functions.
All the drivers in testing work fine:
* virtio-blk is used for the only disk in the VM, IO works fine before
and after.
* virtio-console:
