Sure - domctl.h must not be included from xen-mca.h in any case,
you'll need to move the type declaration if you want to use it outside
the domctl/sysctl set.

You can't disable CONFIG_COMPAT anymore, but I think you should
be able to tweak the CONFIG_COMPAT section in
xen/arch/x86/cpu/mcheck/mce.c in a way to allow your new code to
be built without doing anything compat-related for the new
structures. But maybe removing the domctl.h dependency already
clarifies matters.
