ARM: 8663/1: wire up HWCAP/HWCAP2 feature bits to the CPU modalias

2017-03-30T18:45:52Z

Wire up the generic support for exposing CPU feature bits via the modalias in /sys/device/system/cpu. This allows udev to automatically load modules for things like crypto algorithms that are implemented using optional instructions. Since it is non-trivial to transparantly support both HWCAP and HWCAP2 capabilities in the cpu_feature() macro (which allows a module's hwcap dependency and init routine to be declared using a single invocation of module_cpu_feature_match()), support only HWCAP2 for now, which covers the capabilities that are most likely to be useful in this manner. Module dependencies on HWCAP will need to be declared explicitly via a MODULE_DEVICE_TABLE(cpu, ...) declaration. Signed-off-by: Ard Biesheuvel Signed-off-by: Russell King
