  "message": "cpu: add generic support for CPU feature based module autoloading\n\nThis patch adds support for advertising optional CPU features over udev\nusing the modalias, and for declaring compatibility with/dependency upon\nsuch a feature in a module.\n\nThe mapping between feature numbers and actual features should be provided\nby the architecture in a file called \u003casm/cpufeature.h\u003e which exports the\nfollowing functions/macros:\n- cpu_feature(FEAT), a preprocessor macro that maps token FEAT to a\n  numeric index;\n- bool cpu_have_feature(n), returning whether this CPU has support for\n  feature #n;\n- MAX_CPU_FEATURES, an upper bound for \u0027n\u0027 in the previous function.\n\nThe feature can then be enabled by setting CONFIG_GENERIC_CPU_AUTOPROBE\nfor the architecture.\n\nFor instance, a module that registers its module init function using\n\n  module_cpu_feature_match(FEAT_X, module_init_function)\n\nwill be probed automatically when the CPU\u0027s support for the \u0027FEAT_X\u0027\nfeature is advertised over udev, and will only allow the module to be\nloaded by hand if the \u0027FEAT_X\u0027 feature is supported.\n\nSigned-off-by: Ard Biesheuvel \u003card.biesheuvel@linaro.org\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\n",
