Subject: [PATCH 5/6] powerpc/sparse: Pass endianness to sparse
Date: Mon,  4 Jul 2016 17:09:41 +1000	[thread overview]
Message-ID: <1467616182-30886-5-git-send-email-dja@axtens.net> (raw)
In-Reply-To: <1467616182-30886-1-git-send-email-dja@axtens.net>

Explicitly give sparse an endianness in the Makefile, so that it
doesn't get confused.

Normally we have #ifdef one and #else the other, so it doesn't usually
matter, but we have been bitten by it before, and indeed this patch
fixes a number of sparse errors.
