Konstantin Belousov 36596c2a29 Detect x2APIC mode on boot and obey it. ... If BIOS performed hand-off to OS with BSP LAPIC in the x2APIC mode, system usually consumes such configuration without a notice, since x2APIC is turned on by OS if possible (nop). But if BIOS simultaneously requested OS to not use x2APIC, code assumption that that xAPIC is active breaks. In my opinion, we cannot safely turn off x2APIC if control is passed in this mode. Make madt.c ignore user or BIOS requests to turn x2APIC off, and do not check the x2APIC black list. Just trust the config and try to continue, giving a warning in dmesg.
