Subject: [PATCH 20/31] arm,sparc,unicore32: remove flush_icache_user_range
Date: Sun, 10 May 2020 09:54:59 +0200	[thread overview]
Message-ID: <20200510075510.987823-21-hch@lst.de> (raw)
In-Reply-To: <20200510075510.987823-1-hch@lst.de>

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>.
