Subject: [PATCH v2 4/8] arm: kdump: skip indirection page when crashing
Date: Wed, 5 May 2010 09:54:16 +0300 [thread overview]
Message-ID: <77df4d5693bd8cf03b47b0d67b32c2dc578fd63f.1273041358.git.ext-mika.1.westerberg@nokia.com> (raw)
In-Reply-To: <cover.1273041357.git.ext-mika.1.westerberg@nokia.com>
When we are crashing there is no indirection page in place. Only control page is
present.
