From 6e596084833b95662dfe90e1f30d83ccbd64575c Mon Sep 17 00:00:00 2001
From: Robert Moore <Robert.Moore@intel.com>
Date: Wed, 5 Mar 2014 14:12:01 +0800
Subject: ACPICA: Revert "Headers: Deploy #pragma pack (push) and (pop)."

This reverts commit aae576e5faefa8ba70647efa320d4747b6375f1e.
Push and Pop are not portable "enough", and caused problems for
some ACPICA customers.
