The vdpa devices that use va addresses neeeds these maps shared. Otherwise,
vhost_vdpa checks will refuse to accept the maps.
Discovered this issue while testing SVQ with vdpa sim, now defaulting to
use_va=on.
v2:
* Use PROT_READ|PROT_WRITE instead of O_RDWR. The latter does not work for
mmap.
Eugenio Pérez (3):
vdpa: do not block migration if device has cvq and x-svq=on
vdpa: reorder vhost_vdpa_net_cvq_cmd_page_len function
vdpa: map shadow vrings with MAP_SHARED
