Subject: [patch 7/8] Immediate Values Powerpc Optimization Fix
Date: Thu, 06 Sep 2007 16:02:35 -0400	[thread overview]
Message-ID: <20070906200316.027744569@polymtl.ca> (raw)
In-Reply-To: 20070906200228.086651361@polymtl.ca

[-- Attachment #1: immediate-values-powerpc-optimization-fix.patch --]
[-- Type: text/plain, Size: 1371 bytes --]

Fix a bad call to flush_icache_range(). The second parameter is the end address
of the range, not the length.
