Hi all, After merging the final tree, today's linux-next build (powerpc allyesconfig) failed like this: drivers/video/udlfb.c: In function 'dlfb_compress_hline': drivers/video/udlfb.c:421: error: implicit declaration of function 'prefetch_range' Presumably caused by commit e66eed651fd1 ("list: remove prefetching from regular list iterators"). We need to include preempt.h explictly, now. I have included this patch for today: From: Stephen Rothwell <sfr@canb.auug.org.au> Date: Fri, 20 May 2011 16:29:01 +1000 Subject: [PATCH] udlfb: include prefetch.h explicitly Commit e66eed651fd1 ("list: remove prefetching from regular list iterators") removed the include of prefetch.h from list.h, so we need to include it explicitly, now. fixes this build error on powerpc: drivers/video/udlfb.c: In function 'dlfb_compress_hline': drivers/video/udlfb.c:421: error: implicit declaration of function 'prefetch_range' Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> --- drivers/video/udlfb.c | 1 + 1 files changed, 1 insertions(+), 0 deletions(-)
