Subject: [PATCH v2 4/5] ARM: mm: remove broken condition check for v4 flushing
Date: Mon, 25 Mar 2013 18:17:38 +0000 [thread overview]
Message-ID: <1364235459-17672-5-git-send-email-will.deacon@arm.com> (raw)
In-Reply-To: <1364235459-17672-1-git-send-email-will.deacon@arm.com>
There's no point having a conditional cache flush if we don't know the
state of the condition beforehand.
This patch makes the cacheflush in v4_flush_user_cache_range
unconditional.
