Subject: [PATCH 6/9] Revert "x86/boot: Map more than the first 16MB"
Date: Thu, 18 Jan 2018 18:16:49 +0000	[thread overview]
Message-ID: <20180118181652.26397-7-wei.liu2@citrix.com> (raw)
In-Reply-To: <20180118181652.26397-1-wei.liu2@citrix.com>

This reverts commit 7d6f958d9d18c54017f5ef6e299a08037f035747.

Now we have PVH info relocation support, this change is no longer
needed.
