Subject: [PATCH 06/12][RFC v3] x86, hibernate: Rename temp_level4_pgt to temp_pgt
Date:   Wed, 19 Sep 2018 15:42:39 +0800
Message-Id: <5e9003beb492444e98a148dfb9413593e53da51c.1537275915.git.yu.c.chen@intel.com>

Precedence: bulk

From: Zhimin Gu <kookoo.gu@intel.com>

As 32bit system is not using 4-level page, rename it
to temp_pgt so that it can be reused for both 32bit
and 64bit hibernation.

No functional change.
