Intel processors which don't report cache information via cpuid(2) or cpuid(4) need quirk code in the legacy_cache_size callback to report this data. For Intel that callback is is intel_size_cache(). This patch enables calling of cpu_detect_cache_sizes() inside of init_intel() and hence the calling of the legacy_cache callback in intel_size_cache(). Adding this call will ensure that PIII Tualatin currently in intel_size_cache() and Quark SoC X1000 being added to intel_size_cache() in this patch will report their respective cache sizes. This model of calling cpu_detect_cache_sizes() is consistent with AMD/Via/Cirix/Transmeta and Centaur. Also added is a string to idenitfy the Quark as Quark SoC X1000 giving better and more descriptive output via /proc/cpuinfo Adding cpu_detect_cache_sizes to init_intel() will enable calling of intel_size_cache() on Intel processors which currently no code can reach. Therefore this patch will also re-enable reporting of PIII Tualatin cache size information as well as add Quark SoC X1000 support.
