[PATCH -next] xen: fix header export to userspace

[Randy Dunlap]

From: Randy Dunlap <randy.dunlap@xxxxxxxxxx>

scripts/headers_install.pl prevents "__user" from being exported
to userspace headers, so just use compiler.h to make sure that
__user is defined and avoid the error.

unifdef: linux-next-20101112/xx64/usr/include/xen/privcmd.h.tmp: 79: Premature EOF (#if line 33 depth 1)
