Subject: [PATCH 2.6.34-rc2] sh: Fix FDPIC binary loader
Date: Fri, 26 Mar 2010 09:55:38 +0000	[thread overview]
Message-ID: <4BAC849A.9090403@codesourcery.com> (raw)

Ensure that the aux table is properly initialized, even when optional 
features are missing. Without this, the FDPIC loader did not work.
