X-Git-Tag: v5.19-rc1~204^2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=991d8d8142cad94f9c5c05db25e67fa83d6f772a;p=thirdparty%2Fkernel%2Flinux.git

topology: Remove unused cpu_cluster_mask()

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")
