This reverts commit d085eb8ce7 ("vhost: disable for OABI")
With commit "virtio: force spec specified alignment on types"
in place, we force proper alignment for all structures,
so there's no longer a reason to blacklist OABI.

This option allows vhost to support guests with a different byte

ordering from host while using legacy virtio.
|

|
Userspace programs can control the feature using the
|
|
VHOST_SET_VRING_ENDIAN and VHOST_GET_VRING_ENDIAN ioctls.
|
|
|
|
This is only useful on a few platforms (ppc64 and arm64). Since it
|
|
adds some overhead, it is disabled by default.

If unsure, say "N".
