    sched/fair: Convert arch_scale_cpu_capacity() from weak function to #define · 8cd5601c
    Morten Rasmussen authored
    Bring arch_scale_cpu_capacity() in line with the recent change of its
    arch_scale_freq_capacity() sibling in commit dfbca41f ("sched:
    Optimize freq invariant accounting") from weak function to #define to
    allow inlining of the function.
    
    While at it, remove the ARCH_CAPACITY sched_feature as well. With the
    change to #define there isn't a straightforward way to allow runtime
    switch between an arch implementation and the default implementation of
    arch_scale_cpu_capacity() using sched_feature. The default was to use
    the arch-specific implementation, but only the arm architecture provides
    one and that is essentially equivalent to the default implementation.
