    x86, debug: tone down arch/x86/kernel/mpparse.c debugging printk · eeb0d7d1
    Rene Herman 提交于
    commit 11a62a05 turns some formerly
    nopped debugging printks in arch/x86/kernel/mppparse.c into regular
    ones. The one at the top of smp_scan_config() in particular also
    prints on !CONFIG_SMP/CONFIG_X86_LOCAL_APIC kernels and UP machines
    without anything resembling MP tables which makes their lowly UP
    owners wonder...
    
    Turn the former Dprintk()s into apic_printk()s instead meaning that
    their printing is dependent on passing the apic=verbose (or =debug)
    command line param.
    
    On 32-bit, "apic" is a __setup() param which isn't early enough
    for this code and therefore needs a followup changing it into an
    early_param(). On 64-bit, it already is.
