    powerpc: Add module autoloading based on CPU features · 4a120276
    Alastair D'Silva authored
    This patch provides the necessary infrastructure to allow drivers
    to be automatically loaded via udev. It implements the minimum
    required to be able to use module_cpu_feature_match() to trigger
    the GENERIC_CPU_AUTOPROBE mechanisms.
    
    The features exposed are a mirror of the cpu_user_features
    (converted to an offset from a mask). This decision was made to
    ensure that the behavior between features for module loading and
    userspace are consistent.
