Subject: [patch 37/54] microblaze: use asm-generic/cacheflush.h
Date: Sun, 07 Jun 2020 21:42:04 -0700 [thread overview]
Message-ID: <20200608044204.kenS9FuTG%akpm@linux-foundation.org> (raw)
In-Reply-To: <20200607212615.b050e41fac139a1e16fe00bd@linux-foundation.org>
From: Christoph Hellwig <hch@lst.de>
Subject: microblaze: use asm-generic/cacheflush.h
Microblaze needs almost no cache flushing routines of its own. Rely on
asm-generic/cacheflush.h for the defaults.
