Hi Rusty,
Today's linux-next build (powerpc ppc64_defconfig) failed like this:
arch/powerpc/platforms/cell/spu_base.c: In function 'mm_needs_global_tlbie':
arch/powerpc/platforms/cell/spu_base.c:117: error: implicit declaration of function '__cpus_setall'
Caused by commit 20ec1a8465bd6d2e7e68fa5a7b09309c920b4792
("cpumask:add-struct-cpumask") which removed __cpus_setall from
include/linux/cpumask.h.
I applied the hack patch below (which is probably not what we want).
