When sending patches to -stable, please add "CC: stable
<stable@kernel.org> to the patch itself in the signed-off-by area, that
way we get notified automatically when it goes into Linus's tree so that
we can then know to apply it to the tree.  Otherwise it's a tough job to
try to track all of these knowing when to watch out for them to be
committed.

Can you please resend them to stable@kernel.org when they do go into
Linus's tree?

thanks,
