From fab4610583855d544394320d47fccb43305a6398 Mon Sep 17 00:00:00 2001 From: Lv Zheng Date: Wed, 8 Jan 2014 13:43:40 +0800 Subject: ACPICA: Cleanup the option of forcing the use of the RSDT. This change adds a runtime option that will force ACPICA to use the RSDT instead of the XSDT. Although the ACPI spec requires that an XSDT be used instead of the RSDT, the XSDT has been found to be corrupt or ill-formed on some machines. This option is already in the Linux kernel. When it is back ported to ACPICA, code is re-written to follow ACPICA coding style. This patch is the generation of the integration.
