Sorry, quick follow up.

https://github.com/raspberrypi/linux/issues/1650 is a typical response from
the Raspberrypi folks about this:

    Future rpi- branches (branches that aren't yet the main development
    branch, currently rpi-4.4.y) are rebased against upstream commits.
    Once we start making releases from a branch we stop rebasing and
    start merging.

    The commit you refer to still exists but with a different commit
    ID. You need to tell whoever gave you the hash that bookmarking
    commits in our future branches is futile because they are regularly
    rebased.

Thanks,
