[PATCH] NetBSD: use system-provided headers

Posted by Manuel Bouyer 1 week, 5 days ago
From: Manuel Bouyer <bouyer@netbsd.org>

On NetBSD use the system-provided headers for ioctl and related definitions,
they are up to date and have more chances to match the kernel's idea of
the ioctls and structures.
Remove now-unused NetBSD/evtchn.h and NetBSD/privcmd.h.
Don't fail install if xen/sys/*.h are not present.

This will mask real error on non-NetBSD OSes. My make-foo is very bad,
but maybe you could do something like:

if [ "$(XEN_OS)" != "NetBSD" ]; then \
	$(INSTALL_DATA) xen/sys/*.h $(DESTDIR)$(includedir)/xen/sys; \
fi

Or maybe check whether the directory is not empty before attempting
the install?

Thanks, Roger.
