Subject: [PATCH 2/9] powerpc: Move {d, i, u}cache_bsize definitions to a common place
Date: Sun,  8 Jan 2017 17:31:43 -0600	[thread overview]
Message-ID: <20170108233150.15353-2-benh@kernel.crashing.org> (raw)
In-Reply-To: <20170108233150.15353-1-benh@kernel.crashing.org>

The variables are defined twice in setup_32.c and setup_64.c, do it
once in setup-common.c instead
