    Subject[PATCH v4 0/5] ARM: topology: set the capacity of each cores for big.LITTLE
    Date
    This patchset creates an arch_scale_freq_power function for ARM, which is used 
    to set the relative capacity of each core of a big.LITTLE system. It also removes
    the broken power estimation of x86.

    Modification since v3:
    - Add comments
    - Add optimization for SMP system
    - Ensure that capacity of a CPU will be at most 1

    Modification since v2:
    - set_power_scale function becomes static
    - Rework loop in update_siblings_masks
    - Remove useless code in parse_dt_topology

    Modification since v1:
    - Add and update explanation about the use of the table and the range of the value
    - Remove the use of NR_CPUS and use nr_cpu_ids instead
    - Remove broken power estimation of x86

    Peter Zijlstra (1):
    sched, x86: Remove broken power estimation

    Vincent Guittot (4):
    ARM: topology: Add arch_scale_freq_power function
    ARM: topology: factorize the update of sibling masks
    ARM: topology: Update cpu_power according to DT information
    sched: cpu_power: enable ARCH_POWER
