39  * XXPV	This is maintained by hand :(
40  *
41  * Unfortunately native Xen currently uses the same namespace as the Solaris
42  * errno namespace but with (some) different numeric values.
43  *
44  * This set of errno values match Xen 3.0.3; sigh.
45  *
46  * In a better world, Xen would make it's namespace explicitly different
47  * e.g. something like below.
