Subject: [PATCH v4 04/22] x86, ACPI: Search buffer above 4G in second try for acpi override tables
Date: Thu, 11 Apr 2013 17:55:50 -0700 [thread overview]
Message-ID: <1365728168-32067-5-git-send-email-yinghai@kernel.org> (raw)
In-Reply-To: <1365728168-32067-1-git-send-email-yinghai@kernel.org>
Now we only search buffer for override acpi table under 4G.
In some case, like user use memmap to exclude all low ram,
we may not find range for it under 4G.
Do second try to search above 4G.
