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

Hi all,

After merging the powerpc tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

arch/powerpc/include/asm/setup.h: Assembler messages:
arch/powerpc/include/asm/setup.h:6: Error: Unrecognized opcode: `extern'
make[2]: *** [arch/powerpc/kernel/head_64.o] Error 1

Caused by commit a9c0f41b3a64 ("powerpc: Add printk companion for
ppc_md.progress").  Clearly not build tested for 64 but powerpc :-(

I have used the version of the powerpc tree from next-20110630 for today.
