Subject: [RFC PATCH 04/11] powerpc/prom_init: Replace __initdata with __prombss when applicable
Date: Thu, 31 May 2018 14:33:42 +1000 [thread overview]
Message-ID: <20180531043349.24783-5-benh@kernel.crashing.org> (raw)
In-Reply-To: <20180531043349.24783-1-benh@kernel.crashing.org>
This replaces all occurrences of __initdata for uninitialized
data with a new __prombss
Currently __promdata is defined to be __initdata but we'll
eventually change that.
