Fairly obviously, we need to clean up the hard-coded "linux" names used
in includes. This is the first step in a number of changes around
letting dom0 build on something other than Linux.

What are the plans for these headers when the Linux kernel lives in some
place other than the xen tree itself? We'd like to be able to share the
structure definitions, but our ioctl values will differ from Linux's...

I'd prefer an interfacing library (or libraries) that can target Linux interfaces, Sun interfaces, etc. This would avoid inclusion of kernel interface headers outside that shim library.

Maybe this only needs to be done for evtchn interfaces. I would have hoped that libxenctrl and libxenguest would hide privcmd interfaces. I wonder why so many things include <linux/privcmd.h>?
