[Xen-devel] [PATCH v2 03/23] x86: enclose hvm_op and dm_op in CONFIG_HVM in relevant tables

[Wei Liu <wei.liu2@xxxxxxxxxx>]

PV guest (Dom0) needs to able to use these two hypercalls in order to
serve HVM guests. But if xen doesn't support HVM at all there is no
point in exposing them to PV guests.

v2:
1. Merge two CONFIG_HVMs together
2. Also change args table
