2009-03-18[S390] topology: define SD_MC_INIT to fix performance regressionHeiko Carstens
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>
2009-01-01cpumask: Introduce topology_core_cpumask()/topology_thread_cpumask(): s390Rusty Russell
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>
2008-12-26cpumask: cpu_coregroup_mask(): s390Rusty Russell
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>
