    cpufreq: governor: Implement per policy instances of governors · 4d5dcc42
    Viresh Kumar authored
    Currently, there can't be multiple instances of single governor_type.
    If we have a multi-package system, where we have multiple instances
    of struct policy (per package), we can't have multiple instances of
    same governor. i.e. We can't have multiple instances of ondemand
    governor for multiple packages.
    
    Governors directory in sysfs is created at /sys/devices/system/cpu/cpufreq/
    governor-name/. Which again reflects that there can be only one
    instance of a governor_type in the system.
    
    This is a bottleneck for multicluster system, where we want different
    packages to use same governor type, but with different tunables.
    
    This patch uses the infrastructure provided by earlier patch and
    implements init/exit routines for ondemand and conservative
    governors.
