Subject: [patch 08/24] Blackfin: fix command line corruption with DEBUG_DOUBLEFAULT
Date: Fri, 17 Jul 2009 13:08:59 -0700 [thread overview]
Message-ID: <20090717201230.590698517@mini.kroah.org> (raw)
In-Reply-To: <20090717201639.GA14209@kroah.com>
[-- Attachment #1: blackfin-fix-command-line-corruption-with-debug_doublefault.patch --]
[-- Type: text/plain, Size: 1409 bytes --]
2.6.30-stable review patch. If anyone has any objections, please let us know.
------------------
From: Mike Frysinger <vapier@gentoo.org>
commit 37082511f06108129bd5f96d625a6fae2d5a4ab4 upstream.
Commit 6b3087c6 (which introduced Blackfin SMP) broke command line passing
when the DEBUG_DOUBLEFAULT config option was enabled. Switch the code to
using a scratch register and not R7 which holds the command line.
