[Xen-ia64-devel] [PATCH 2/5] Add XEN_DOMCTL_set_opt_feature

[Alex Williamson <alex.williamson@xxxxxx>]

   This one will also be sent to xen-devel if we decided to use this
method.  HYPERVISOR_opt_feature only sets features for the current
domain, so it seems we need a domctl version to make use of it from
domain builder code.  I was uncomfortable adding arch specific flags to
XEN_DOMCTL_arch_setup, so took this approach.  I think it provides more
flexibility in specifying opt_features in the builder code, as seen in
the last patch.  NB - I'll also include header updates for Linux files
when I send this upstream.
