Rusty Russell 6f7a321d5f [S390] cpumask: remove cpu_coregroup_map
Impact: cleanup

cpu_coregroup_mask is the New Hotness.

As S/390 uses theirs internally, so we just make it static.

Heiko Carstens f55d63854e [S390] topology: define SD_MC_INIT to fix performance regression
The default values for SD_MC_INIT cause an additional cpu usage of up
to 40% on some network benchmarks compared to the plain SD_CPU_INIT
values. So just define SD_MC_INIT to SD_CPU_INIT.
More tuning needs to be done.

Rusty Russell 2bb23a63f2 cpumask: Introduce topology_core_cpumask()/topology_thread_cpumask(): s390
Impact: New API

The old topology_core_siblings() and topology_thread_siblings() return
a cpumask_t; these new ones return a (const) struct cpumask *.

Rusty Russell 9be3eec2c8 cpumask: cpu_coregroup_mask(): s390
Like cpu_coregroup_map, but returns a (const) pointer.

Compile-tested on s390 (defconfig).
