Subject: linux-next: build failure after final merge (arm tree)

Hi Russell,

After merging the scsi-post-merge tree, today's linux-next build (sparc32
defconfig) failed like this:

arch/sparc/mm/sun4c.c: In function 'sun4c_update_mmu_cache':
arch/sparc/mm/sun4c.c:1943: error: 'pte' undeclared (first use
in this function)

Caused by commit 2dca0ca96ac340fbf4f9e0741dcf58ff3677e994 ("MM: Pass a
PTE pointer to update_mmu_cache() rather than the PTE itself").

I applied the following patch for today. It may not be correct.

Damn.

It looks correct to me - I'll merge it into the original commit tonight
unless David provides me with an alternative patch.

Thanks.
