From 09b8b1fce7688958f44884135b83fb857eb6e1b6 Mon Sep 17 00:00:00 2001 From: Lv Zheng Date: Thu, 31 Oct 2013 09:30:16 +0800 Subject: ACPICA: Update RSDP table definitions. This patch updates RSDP table header definitions as such enhancement has been made in ACPICA upstream already. It ports that change to the Linux source to reduce source code differences between Linux and ACPICA upstream. This patch does not affect the generation of the Linux kernel binary.
