Impact: refactor, speed up and robustize code In case if apic was disabled by kernel option or by hardware limits we can use dummy operations in apic->write to simplify the ack_APIC_irq() code. At the lame time the patch fixes the missed EOI in do_IRQ function (which has place if kernel is compiled as X86-32 and interrupt without handler happens where apic was not asked to be disabled via kernel option). Note that native_apic_write_dummy() consists of WARN_ON_ONCE to catch any buggy writes on enabled APICs. Could be removed after some time of testing.
