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

[Stephen Rothwell]

Hi all,

After merging the final tree, today's linux-next build (sparc64 defconfig)
failed like this:

In file included from arch/sparc/include/asm/tlbflush_64.h:4:0,
                 from arch/sparc/include/asm/tlbflush.h:4,
                 from arch/sparc/include/asm/pgtable_64.h:961,
                 from arch/sparc/include/asm/pgtable.h:4,
                 from arch/sparc/mm/tsb.c:10:
include/linux/mm.h: In function 'pgtable_init':
include/linux/mm.h:1391:2: error: implicit declaration of function 
'pgtable_cache_init' [-Werror=implicit-function-declaration]
In file included from arch/sparc/include/asm/pgtable.h:4:0,
                 from arch/sparc/mm/tsb.c:10:
arch/sparc/include/asm/pgtable_64.h: At top level:
arch/sparc/include/asm/pgtable_64.h:978:13: error: conflicting types for 
'pgtable_cache_init' [-Werror]
include/linux/mm.h:1391:2: note: previous implicit declaration of 
'pgtable_cache_init' was here

Caused by commit ea1e7ed33708 ("mm: create a separate slab for page->ptl
allocation") from Linus' tree.  I have not seen that patch in linux-next
before today :-(

I have reverted that commit for today.
