A few SpeedStep-capable systems don't perform according to specification: the CPUID and/or some MSRs don't tell us the CPU is SpeedStep capable even though it definitely is. Allow a relaxed checking for one such issue by a module parameter only available if a config option is turned on. This is done to avoid the risk of doing invalid speedstep instructions on systems which do not support it, and which might even lead to (hardware) failure. Patch originally from Andres Aeriksson (?) aeriksson at fastmail (dot) fm

From Dominik.. The different P-4-M steppings have different "ebx" values. Analyze it correctly to sort out Pentium-4-based Celerons.

From: Dominik Brodowski <linux@dominikbrodowski.de> Too many users use the p4-clockmod cpufreq driver instead of the more advanced speedstep-centrino, speedstep-ich or even acpi drivers. All of the latter (usually) provide voltage scaling, while the p4-clockmod driver only offers a variant of frequency scaling. So, warn users if they try out this driver instead. Also, instead of using a local copy, use the speedstep_lib infrastructure for detecting the processor speed. Adding the Pentium-M get_frequency function to that module only costs about 200 bytes in object size.

From Dominik Brodowski. - separate functions which might be useful for speedstep-piix4, speedstep-via or speedstep-bios into a new speedstep-lib.c. - clean up speedstep-ich as it will only be used for ICH-based chipsets in future. - remove now-obsolete speedstep_coppermine parameter
