Hi,

There doesn't seem to be much more discussion about this, so let's
kick it along a bit. I tried to reclaim a page flag because I can't
bring myself to ifdef it to 64-bit only, but otherwise the patches
don't depend on each other at all.

Thanks,
Nick

Seeing as Mel said he would test it (and maybe Dave could as well), I
will post my patches again. There was a couple of page flags bugs pointed
out last time, which should be fixed.

Thanks,
Nick

I cleaned up the changelog a bit and made a few tweaks to patch 1 as
described in my reply to Hugh. Resending with SOBs.

Thanks,
Nick
