+Subject: [PATCH 139/152] Reduce timer event frequency by 10
+
+Timer event to keep grub msec counter was running at 1000HZ. This was too
+fast for UEFI timer driver and resulted in a 10x slowdown in grub time
+versus wallclock. Reduce the timer event frequency and increase tick
+increment accordingly to keep better time.
