    Subject[PATCH 07/11] Convert um to use read_persistent_clock
    Date
    This patch converts the um arch to use read_persistent_clock().
    This allows it to avoid accessing xtime and wall_to_monotonic
    directly.

    This patch is un-tested, so any help by testers or maintainers would
    be greatly appreciated!
