linux-next: build failure after merge of the final tree

linux-next: build failure after merge of the final tree

[Stephen Rothwell]

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'

linux-next: build failure after merge of the final tree (fbdev tree related)

Hi all,

After merging the final tree, today's linux-next build (powerpc
allyesconfig) failed like this:

drivers/video/i740fb.c: In function 'i740fb_remove':
drivers/video/i740fb.c:1192:7: error: 'par' undeclared (first use in this function)

Caused by commit 5350c65f4f15 ("Resurrect Intel740 driver: i740fb") from
the fbdev tree.  CONFIG_MTRR is not defined for this build ...

I have reverted that commit for today.

Thanks for fixing my stupid bug. I thought that I tested it without 
CONFIG_MTRR. But obviously didn't.

linux-next: build failure after merge of the final tree (fbdev tree related)

Hi all,

After merging the final tree, today's linux-next build (powerpc
ppc44x_defconfig) failed like this:

Caused by commit 353846fb8bb7 ("video: xilinxfb: Use standard variable
name convention") from the fbdev tree.

I have applied the following fix patch for today:

Thanks, I have applied this to the fbdev tree.
