[Xen-devel] [PATCH] Fix xc_hvm_save/restore for non-x86 builds

[Alex Williamson <alex.williamson@xxxxxx>]

   Tools currently won't build on non-x86 due to xc_hvm_save/restore
only being built for CONFIG_HVM, but called from xcutils regardless.
This patch adds stub functions for those of us that don't support HVM
save/restore just yet.  Thanks,

        Alex
