Dave,

Here is this week's round of fixes. Admittedly not all of them are
regressions with entries at bugzilla.kernel.org -- hopefully that is not
a hard and fast requirement. :-)

I think everything here is suitable for 2.6.27. Please let me know if
there are problems.

Thanks!

John

This one should be already in Yi's queue.The patch also address the
allocation error path. It's coauthored with Ian (out of Intel) so we
send it out just for record ... not sure what's the protocol.

Either rebase it or send it as-is -- I'm sure I can resolve the
conflict. I just don't see much point in waiting to resolve such a
simple issue.
