Maintainers are apparently those under "PARAVIRT_OPS INTERFACE".
CCs added.

This misnamed CONFIG_DEBUG_PAGE_TYPE (it's not a Kconfig variable) has
about 120 lines debug code dangling on it.  So, replacing it by #if 0
will hopefully motivate a kind janitor to send a removal patch for that
debug code eventually.  I don't do so just now because that code went in
between 2.6.20 and 2.6.21-rc1, i.e. not so long ago.
