[PATCH 11/32] ACPICA: Tables: Enable default 64-bit FADT addresses favor.
From: Lv Zheng
Date: Thu Jun 18 2015 - 23:39:57 EST
ACPICA commit 4da56eeae0749dfe8491285c1e1fad48f6efafd8
With enough protections, this patch re-enables 64-bit FADT addresses by
default. If regressions are reported against such change, this patch should
be bisected and reverted.
Note that 64-bit FACS favor and 64-bit firmware waking vector favor are
excluded by this commit in order not to break OSPMs. Lv Zheng.
