*	[S390] topology: use default MC domain initializer	Heiko Carstens	2010-08-09
\| \| \| \| \| \| \| \| \| \|	Use default MC sched domain initializer, since performance meassurements finally showed that this is indeed better. Besides the fact that the powersavings flags functions didn't make too much sense, but were unused anyway.

*	[S390] topology: expose core identifier	Heiko Carstens	2010-05-17
\| \| \| \| \| \| \| \| \|	Provide a topology_core_id define which makes sure that the contents of /sys/devices/system/cpu/cpuX/topology/core_id indeed do contain the core id and not always 0.

*	cpumask: remove obsolete topology_core_siblings and ↵	Rusty Russell	2009-09-23
\| \| \| \| \| \| \| \|	topology_thread_siblings: s390 There were replaced by topology_core_cpumask and topology_thread_cpumask. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
*	[S390] cpumask: remove cpu_coregroup_map	Rusty Russell	2009-03-26
\| \| \| \| \| \| \| \| \| \| \|	Impact: cleanup cpu_coregroup_mask is the New Hotness. As S/390 uses theirs internally, so we just make it static. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
*	[S390] topology: define SD_MC_INIT to fix performance regression	Heiko Carstens	2009-03-18
\| \| \| \| \| \| \| \| \| \|	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. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
*	cpumask: Introduce topology_core_cpumask()/topology_thread_cpumask(): s390	Rusty Russell	2008-12-31
\| \| \| \| \| \| \| \| \| \|	Impact: New API The old topology_core_siblings() and topology_thread_siblings() return a cpumask_t; these new ones return a (const) struct cpumask *. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Mike Travis <travis@sgi.com>
*	cpumask: cpu_coregroup_mask(): s390	Rusty Russell	2008-12-26
\| \| \| \| \| \| \| \| \|	Like cpu_coregroup_map, but returns a (const) pointer. Compile-tested on s390 (defconfig). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Mike Travis <travis@sgi.com>
