Subject: [PATCH v2 01/28] csky,sparc: Declare flush_dcache_folio()
Date: Mon,  8 Nov 2021 04:05:24 +0000	[thread overview]
Message-ID: <20211108040551.1942823-2-willy@infradead.org> (raw)
In-Reply-To: <20211108040551.1942823-1-willy@infradead.org>

These architectures do not include asm-generic/cacheflush.h so need
to declare it themselves.

Fixes: 08b0b0059bf1 ("mm: Add flush_dcache_folio()")
Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org>
