From 009c4cbe99bea2da53f29ad685975a36f38c001c Mon Sep 17 00:00:00 2001 From: Bob Moore Date: Wed, 12 Nov 2008 15:34:52 +0800 Subject: ACPICA: Add global pointer for FACS table to simplify FACS access Use a global pointer instead of using AcpiGetTableByIndex for each FACS access. This simplifies the code for the Global Lock and the Firmware Waking Vector(s).

All other acpica headers are "private" and should not be included by acpica users. One new file, accommon.h is used to include the commonly used private headers for acpica code generation. Future plans are to move all private headers to a new subdirectory.
