    fix maxcpus=N parsing · 81340977
    Hugh Dickins 提交于
    Commit 61ec7567 ('ACPI: boot correctly
    with "nosmp" or "maxcpus=0"') broke 'maxcpus=' handling on x86[-64].
    
    maxcpus=N is now having no effect on x86_64, and freezing bootup on i386
    (because of inconsistency with the separate maxcpus parsing down in
    arch/i386, I guess).  That's because early_param parsing is a little
    different from __setup parsing, and needs the "=" omitted: then it seems
    to work as the original commit intended (no mention of IO-APIC in
    /proc/interrupts when maxcpus=0).
