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,
