    parisc: Increase parisc_cache_flush_threshold setting · a58e9d09
    John David Anglin authored
    In testing the "Fix non-access data TLB cache flush faults" change,
    I noticed a significant improvement in glibc build and check times.
    This led me to investigate the parisc_cache_flush_threshold setting.
    It determines when we switch from line flushing to whole cache flushing.
    
    It turned out that the parisc_cache_flush_threshold setting on
    mako and mako2 machines (PA8800 and PA8900 processors) was way too
    small. Adjusting this setting provided almost a factor two improvement
    in the glibc build and check time.
