Subject: linux-next: build failure after merge of the moduleh tree
Date: Fri, 23 Mar 2012 15:51:14 +1100	[thread overview]
Message-ID: <20120323155114.a1779aa050fa05f6191b7dae@canb.auug.org.au> (raw)

Hi Paul,

After merging the moduleh tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/gpu/drm/radeon/si_blit_shaders.c:252:1: error: implicit declaration of function 'BUILD_BUG_ON_ZERO' [-Werror=implicit-function-declaration]
drivers/gpu/drm/radeon/si_blit_shaders.c:252:1: error: initializer element is not constant

Caused by commit 48c0c902e2e6 ("drm/radeon/kms: add support for CP setup
on SI") from Linus' tree interacting with commit 6c03438edeb5 ("kernel.h:
doesn't explicitly use bug.h, so don't include it").

ARRAY_SIZE in kernel.h uses __must_be_array from compiler{-ggc,-intel}.h
which uses BUILD_BUG_ON_ZERO ...  I don;t know if we want to include
bug.h in compiler.h ...

So, for today, I have added the following patch:

From: Stephen Rothwell <sfr@canb.auug.org.au>
Date: Fri, 23 Mar 2012 15:47:07 +1100
Subject: [PATCH] kernel.h: using ARRAY_SIZE needs to include bug.h
