Subject: [PATCH 4/8] x86, mm: Revert back good_end setting for 64bit
Date: Thu, 30 Aug 2012 16:06:11 -0700	[thread overview]
Message-ID: <1346367975-6446-5-git-send-email-yinghai@kernel.org> (raw)
In-Reply-To: <1346367975-6446-1-git-send-email-yinghai@kernel.org>

So we could put page table high again for 64bit.
