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 Date: Fri, 23 Mar 2012 15:47:07 +1100 Subject: [PATCH] kernel.h: using ARRAY_SIZE needs to include bug.h Signed-off-by: Stephen Rothwell --- drivers/gpu/drm/radeon/si_blit_shaders.c | 1 + 1 files changed, 1 insertions(+), 0 deletions(-) diff --git a/drivers/gpu/drm/radeon/si_blit_shaders.c b/drivers/gpu/drm/radeon/si_blit_shaders.c index a7124b4..ec415e7 100644 --- a/drivers/gpu/drm/radeon/si_blit_shaders.c +++ b/drivers/gpu/drm/radeon/si_blit_shaders.c @@ -25,6 +25,7 @@ */ #include +#include #include const u32 si_default_state[] = -- 1.7.9.1 -- Cheers, Stephen Rothwell sfr@canb.auug.org.au
