default_topology[] uses cpu_clustergroup_mask() for the CLS level
(guarded by CONFIG_SCHED_CLUSTER) which is currently provided by x86
(arch/x86/kernel/smpboot.c) and arm64 (drivers/base/arch_topology.c).
Fixes: 778c558f49a2c ("sched: Add cluster scheduler level in core and
related Kconfig for ARM64")

I agree there are no users right now. I probably wrote it like cpu_smt_mask()
and used it in kernel/sched for the wake_affine patch but forgot to remove it
while sending patches without wake_affine.

Hi Peter,
I also received emails which say Greg has put it into drive-core-testing and
driver-core-next.

Damn, I must've missed that. It think git will DTRT and the trees will
merge painlessly.
