Subject: Sync xenio.h with kernel, and apply patch from Jed Davis on port-xen:
 | libxc change #1 is to have xfrd's forked child munmap each 4MB batch | of
 foreign RAM after it's done writing it, rather than unmapping only | the last
 one and letting the process's exit clean up the rest.  This | really does
 look like a simple mistake, and strictly speaking it's not | that big a deal
 -- but on NetBSD, the foreign mappings count against | the process's locked
 memory rlimit as if it were the dom0's own RAM. | | libxc change #2... I
 don't really understand the problem; it has | something to do with live
 migration and the domU releasing | pseudo-physical pages after they were sent
 but before it's suspended. | Except that, for non-live mode, I think it's
 reporting all the holes | in the pseudo-physical range, even though those
 pages haven't been | sent.  In any case, the result is that the restoring
 xfrd fails to | decrease_reservation the pages away.  And I distinctly recall
 this | working at least once under Linux with Xen 2, but I have little idea |
 what NetBSD might be doing differently.

Bump PKGREVISION. This, along with a up to date -current kernel,
make xm (save|restore) work properly for a linux domU.
