Well something is out of sync but I don't think it's me.

Starting over with GPG-verified downloads from kernel.org I get:

$ tar xjf /mnt/t/lib/linux/2.6.17/linux-2.6.17.tar.bz2
$ cd linux-2.6.17
$ bzcat /mnt/t/lib/linux/2.6.18/rc6/patch-2.6.18-rc6.bz2 | patch -p1 -s
$ tar xjf /mnt/t/lib/linux/2.6.18/rc6/mm1/2.6.18-rc6-mm1-broken-out.tar.bz2
$ mv broken-out patches
$ quilt push -a

And like I said, you can even see that git-block.patch, earlier in the series,
creates this problem:

$ quilt applied | fgrep block
git-block.patch
git-block-hack.patch

This is the failing hunk.  The highlighted context line is wrong because
git-block.patch changed it:
