Subject: [PATCH 18/29] arm,sparc,unicore32: remove flush_icache_user_range
Date:   Fri, 15 May 2020 16:36:35 +0200
Message-Id: <20200515143646.3857579-19-hch@lst.de>
In-Reply-To: <20200515143646.3857579-1-hch@lst.de>
References: <20200515143646.3857579-1-hch@lst.de>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

flush_icache_user_range is only used by <asm-generic/cacheflush.h>, so
remove it from the architectures that implement it, but don't use
<asm-generic/cacheflush.h>.
