[PATCH v2 00/24] virtio: config space endian-ness cleanup
Config space endian-ness is currently a mess: fields are
not tagged with the correct endian-ness so it's easy
to make mistakes like instanciating config space in
native endian-ness.
The following patches adding sparse tagging are currently in my tree.
Lightly tested.
As a follow-up, I plan to add new APIs that handle modern config space
in a more efficient way (bypassing the version check).

[PATCH v3 0/8] vdpa_sim: add support for user VA
This series adds support for the use of user virtual addresses in the
vDPA simulator devices.
The main reason for this change is to lift the pinning of all guest memory.
Especially with virtio devices implemented in software.
The next step would be to generalize the code in vdpa-sim to allow the
implementation of in-kernel software devices. Similar to vhost, but using vDPA

[PATCH v2 0/8] vdpa_sim: add support for user VA
v2:
- rebased on Linus' tree, commit ae3419fbac84 ("vc_screen: don't clobber
return value in vcs_read")
- removed `struct task_struct *owner` param (unused for now, maybe
?useful to support cgroups) [Jason]
- add unbind_mm callback [Jason]
- call the new unbind_mm callback during the release [Jason]
- avoid to call bind_mm callback after the reset, since the device
