Subject: [PATCH 21/29] sh: implement flush_icache_user_range
Date: Fri, 15 May 2020 16:36:38 +0200	[thread overview]
Message-ID: <20200515143646.3857579-22-hch@lst.de> (raw)
In-Reply-To: <20200515143646.3857579-1-hch@lst.de>

The SuperH implementation of flush_icache_range seems to be able to
cope with user addresses.  Just define flush_icache_user_range to
flush_icache_range.
