This is solely my fault -- too much time on processes, email, and
documentation, not enough time on the Seattle patches.  And not
enough Seattles to go around for someone else to pick up the slack.

I am aware not everyone is subscribed to linaro-acpi; we use that
for internal review before posting more broadly, which is the only
reason I sent them there.

I'm in the middle of updating them as I have time, based on really
good feedback from Arnd; few of them are terribly new (the very first
posting was [0]) -- it's mostly a matter of rebasing, integrating
updates from AMD and others, and reacting to the comments.  One can
also see what these patches will probably look like via one of the
Fedora kernel trees [1].

[1] https://git.fedorahosted.org/git/kernel-arm64 -- this is
    what I run on an AMD Seattle daily driver, btw, and is used
    in Fedora 21 as well.
