Subject: [PATCH] ARM: zImage: fix Thumb2 breakage
Date: Wed, 08 Jun 2011 23:53:02 -0400 (EDT) [thread overview]
Message-ID: <alpine.LFD.2.00.1106082350500.2142@xanadu.home> (raw)
Commit af3e4fd37a "ARM: 6859/1: Add writethrough dcache support for
ARM926EJS processor" broke Thumb2 compilation by omitting to maintain
the wide encoding for the added branch instructions which made the
ARM926EJ-S record smaller than expected, breaking the record walk code.
