Subject: [PATCH] vhost: let CONFIG_VHOST to be selected by drivers
The defconfig on some archs enable vhost_net or vhost_vsock by
default. So instead of adding CONFIG_VHOST=m to all of those files,
simply letting CONFIG_VHOST to be selected by all of the vhost
drivers. This fixes the build on the archs with CONFIG_VHOST_NET=m in
their defconfig.

OK so I squashed this into the original buggy patch.
Could you please play with vhost branch of my tree on various
arches? If it looks ok to you let me know I'll push
this to next.
With the above part squashed. I've tested all the archs whose defconfig
have VHOST_NET or VHOST_VSOCK enabled.
All looks fine.
Thanks
