Subject: [patch 38/54] m68knommu: use asm-generic/cacheflush.h
Date: Sun, 07 Jun 2020 21:42:06 -0700 [thread overview]
Message-ID: <20200608044206.SQBOGv2M1%akpm@linux-foundation.org> (raw)
In-Reply-To: <20200607212615.b050e41fac139a1e16fe00bd@linux-foundation.org>
From: Christoph Hellwig <hch@lst.de>
Subject: m68knommu: use asm-generic/cacheflush.h
m68knommu needs almost no cache flushing routines of its own. Rely on
asm-generic/cacheflush.h for the defaults.
