X-Git-Tag: submit/tizen_common/20140730.172411~638 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0ed09dccba02daca9afa960d160a74a6f72c4398;p=profile%2Fivi%2Fkernel-x86-ivi.git ACPICA: Tables: Restore old behavor to favor 32-bit FADT addresses. commit 85dbd5801f62b66e2aa7826aaefcaebead44c8a6 upstream. We need to find a smarter way to switch to 64-bit FADT addresses according to the bug report. This patch reverts Linux to the original behavior. Fixes: 0249ed2444d6 (ACPICA: Add option to favor 32-bit FADT addresses.)
