[Xen-devel] [PATCH 7/8] [xen-ppc] Domain Groups: arch-specfic VMM mods

[Chris <hap10@xxxxxxxxxxxxxx>]

xen-ppc:

Architecture-specific code to initialize group data structures and
handle new domgrpctl hypercall.

Untested; it would help if someone with access to PPC hardware would
give this a shot.
