[Xen-devel] [PATCH] Create XEN_DOMCTL_set_opt_feature

   This patch goes along with the guest_os_type domain config patch.
Once we know what the guest OS is in the builder code, we need a
mechanism to set optimization features for that guest.  This is done via
a new XEN_DOMCTL as shown in the patch below.  This only has ia64
specific contents at the moment, but could be expanded for x86.  I
expect the contents of the structure will mostly be architecture
specific.  Thanks,


Xen patch below, identical patch for xenlinux attached.
