From 3aed1012cb8f559a0241569d6ec6b1be23844b05 Mon Sep 17 00:00:00 2001

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.
