    x86: Fix bogus warning in apic_noop.apic_write() · a946d8f1

    apic_noop is used to provide dummy apic functions. It's installed
    when the CPU has no APIC or when the APIC is disabled on the kernel
    command line.
    
    The apic_noop implementation of apic_write() warns when the CPU has
    an APIC or when the APIC is not disabled.
    
    That's bogus. The warning should only happen when the CPU has an
    APIC _AND_ the APIC is not disabled. apic_noop.apic_read() has the
    correct check.
