Subject: [PATCH 2/3] powerpc: remove the symbol __flush_icache_range
Date: Tue, 6 Aug 2013 18:23:31 +0800	[thread overview]
Message-ID: <1375784612-14399-3-git-send-email-haokexin@gmail.com> (raw)
In-Reply-To: <1375784612-14399-1-git-send-email-haokexin@gmail.com>

And now the function flush_icache_range() is just a wrapper which
only invoke the function __flush_icache_range() directly. So we
don't have reason to keep it anymore.
