Hi Rusty,

Today's linux-next build (powerpc allyesconfig) failed like this:

kernel/sched.c: In function 'cpu_to_phys_group':
kernel/sched.c:7437: error: implicit declaration of function 'cpu_sibling_mask'
kernel/sched.c:7437: warning: passing argument 2 of 'cpumask_and' makes pointer from integer without a cast
kernel/sched.c: In function '__build_sched_domains':
kernel/sched.c:7780: warning: passing argument 2 of 'cpumask_and' makes pointer from integer without a cast
kernel/sched.c:7790: warning: passing argument 2 of 'cpumask_and' makes pointer from integer without a cast

Caused by commit 6034a37f9dff70fea021bf3a2dcdc356bccb88b3
("cpumask:use-cpu_sibling_mask") which introduced uses of
cpu_sibling_mask which is only defined for x86 ...

I have reverted that commit for today.
