 Core:

  - Early boot support for the NMI safe timekeeper by utilizing
    local_clock() up to the point where timekeeping is initialized. This
    allows printk() to store multiple timestamps in the ringbuffer which is
    useful for coordinating dmesg information across a fleet of machines.

  - Provide a multi-timestamp accessor for printk()

  - Make timer init more robust by checking for invalid timer flags.

  - Comma vs. semicolon fixes

 Drivers:

  - Support for new platforms in existing drivers (SP804 and Renesas CMT)

  - Comma vs. semicolon fixes
