Subject: [PATCH] ARM: fix regression in IXP4xx clocksource
Date: Wed, 06 Jul 2011 23:02:17 +0200 [thread overview]
Message-ID: <m3liwb15t2.fsf@intrepid.localdomain> (raw)
From: Richard Cochran <richardcochran@gmail.com>
Commit 234b6ceddb4fc2a4bc5b9a7670f070f6e69e0868
clocksource: convert ARM 32-bit up counting clocksources
broke the build for ixp4xx and made big endian operation impossible.
This commit restores the original behaviour.
