Alok - the window for updates for the July 3 release has passed. I also
have some security updates that take precedence, so its unlikely that
the next batch of Hardy updates will get released until mid-July (at the
earliest). If the 2.6.27 merge window has opened by then (and these
patches are accepted), I would prefer that you resubmit these 5 patches
as coming from Linus' tree. It makes it much easier to keep track of
cherry-picks.
