- List-id: Xen developer discussion <xen-devel.lists.xenproject.org>
This is technically an ABI change, but Xen doesn't operate in any environment
where "unsigned int" is differnet to uint32_t, so switch to the explicit form.
This avoids the need to derive (identical) compat logic for handling the
subop.
