[Xen-devel] [PATCH v2 1/5] NetBSDRump: provide evtchn.h

[Wei Liu <wei.liu2@xxxxxxxxxx>]

Xen's build system has a target for rump kernel called NetBSDRump. We
want to build libxc against rump kernel, so we need to copy NetBSD's
evtchn.h to NetBSDRump. This copy is not very likely to diverge from
NetBSD's copy, but we don't preclude such possibility.

The actual implementation of evtch code will be factored out from
libxc's NetBSD osdep code.
