37  * XXPV	This is maintained by hand :(

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