Date: Wed, 28 May 2014 01:29:08 +0800 Message-Id: <815bd8a45e4bd1d78e0ed605f6f542e22c277da6.1401210685.git.lv.zheng@intel.com> X-Mailer: git-send-email 1.7.10 In-Reply-To: References: <38907770.bupFXhytsS@vostro.rjw.lan> Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org From: Lv Zheng 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.
