#1618820 — [PULL] clocksource/arch_timer: Errata workaround infrastructure rework

Hi Daniel,

Please find below the pull request for the arm64 architected timer
workaround infrastructure. As discussed on the list, the first 5
patches are shared with the arm64 tree (and the whole branch is stable
anyway).

Thanks,

	M.
