Subject: linux-next: rr-latest-cpumask/sparc tree build failure

Hi Rusty,

Today's linux-next build (sparc64 defconfig) failed like this:

arch/sparc/mm/init_64.c: In function 'paging_init':
arch/sparc/mm/init_64.c:1802: error: 'CPU_MASK_ALL_PTR' undeclared (first use in this function)
arch/sparc/kernel/smp_64.c: In function 'setup_per_cpu_areas':
arch/sparc/kernel/smp_64.c:1541: error: 'CPU_MASK_ALL_PTR' undeclared (first use in this function)

Caused by commit b46586049330222ccab229a1a1e498e94c5fa5dc
("cpumask:remove-CPU_MASK_ALL_PTR") from the rr-latest-cpumask tree
interacting with commits 21bc149d59288fe43d1ba18a59d874ba6a5f1db9
("sparc64: Make mdesc_fill_in_cpu_data take a cpumask_t pointer") and
63750a3dc53a87a1f5ca42101ea88578b934ab52 ("sparc64: Defer cpu_data()
setup until end of per-cpu data initialization") from the sparc tree.

I applied this patch:
