Qian Cai	509466b7d4	sched/fair: Fix "runnable_avg_yN_inv" not used warnings ... runnable_avg_yN_inv[] is only used in kernel/sched/pelt.c but was included in several other places because they need other macros all came from kernel/sched/sched-pelt.h which was generated by Documentation/scheduler/sched-pelt. As the result, it causes compilation a lot of warnings, kernel/sched/sched-pelt.h:4:18: warning: 'runnable_avg_yN_inv' defined but not used [-Wunused-const-variable=] kernel/sched/sched-pelt.h:4:18: warning: 'runnable_avg_yN_inv' defined but not used [-Wunused-const-variable=] kernel/sched/sched-pelt.h:4:18: warning: 'runnable_avg_yN_inv' defined but not used [-Wunused-const-variable=] ... Silence it by appending the __maybe_unused attribute for it, so all generated variables and macros can still be kept in the same file.

Yuyang Du	76d034edcf	sched/Documentation: Add 'sched-pelt' tool ... Add a user-space program to compute/generate the PELT constants. The kernel/sched/sched-pelt.h header will contain the output of this program.
