[PATCH V3 0/2] qemu: vhost-user: Support Xen memory mapping quirks

[Viresh Kumar <viresh.kumar@xxxxxxxxxx>]

Hello,

This patchset tries to update the vhost-user protocol to make it support special
memory mapping required in case of Xen hypervisor.

The first patch is mostly cleanup and second one introduces a new xen specific
feature.

V2->V3:
- Remove the extra message and instead update the memory regions to carry
  additional data.

- Drop the one region one mmap relationship and allow back-end to map only parts
  of a region at once, required for Xen grant mappings.

- Additional cleanup patch 1/2.

V1->V2:
- Make the custom mmap feature Xen specific, instead of being generic.
- Clearly define which memory regions are impacted by this change.
- Allow VHOST_USER_SET_XEN_MMAP to be called multiple times.
- Additional Bit(2) property in flags.
