A few small fixes since -rc3, most notably an OHCI bug that
would corrupt memory and seems to have been the reason for the "Bad
page flags" bug at least on ppc64 (it's not been reported on x86,
as far as I know, but I don't see why the corruption couldn't have
happened there too).
The full changelog from 2.6.3 is on the ftp-sites along with the
patches and tar-balls, and the BK trees have been updated.
