2017-08-30MIPS: Abstract CPU core & VP(E) ID access through accessor functionsPaul Burton1-1/+1
We currently have fields in struct cpuinfo_mips for the core & VP(E) ID of a particular CPU, and various pieces of code directly access those fields. This patch abstracts such access by introducing accessor functions cpu_core(), cpu_set_core(), cpu_vpe_id() & cpu_set_vpe_id() and having code that needs to access these values call those functions rather than directly accessing the struct cpuinfo_mips fields. This prepares us for changes to the way in which those values are stored in later patches. The cpu_vpe_id() function is introduced even though we already had a cpu_vpe_id() macro for a couple of reasons: 1) It's more consistent with the core, and future cluster, accessors. 2) It ensures a sensible return type without explicit casts. 3) It's generally preferable to use functions rather than macros.

Rename topology_thread_cpumask() to topology_sibling_cpumask() for more consistency with scheduler code.

2014-08-27MIPS: Move CPU topology macros to topology.hHuacai Chen1-0/+8
The correct position is topology.h, and this fix macros redefinition problems for Netlogic.

2014-03-11sched: Remove unused mc_capable() and smt_capable()Bjorn Helgaas1-4/+0
Remove mc_capable() and smt_capable(). Neither is used. Both were added by 5c45bf279d37 ("sched: mc/smt power savings sched policy"). Uses of both were removed by 8e7fbcbc22c1 ("sched: Remove stale power aware scheduling remnants and dysfunctional knobs").
