    x86: Add cpu_detect_cache_sizes to init_intel() add Quark legacy_cache() · aece118e
    Bryan O'Donoghue 提交于
    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.
