I've picked these up (with a few local cleanups), given that some local
testing, and pushed the result to a branch [1] on my git repo.

There are likely to be clashes with the arm64 tree (e.g. for
silicon-errata.txt), and we're also likely to have more arch timer
updates shortly for the GTDT stuff, so I think the best bet is for both
arm64 and the clocksource tree to pull that branch for v4.11.

Alternatively, we could take this all through the arm64 tree, if the
clocksource maintainers are happy with that.

Thoughts?

Thanks,
Mark.
