Changelog since:
v2:
* rebase on top of current master /smp_scan() changes/
v1:
* s/count_cpu/apic_id_init/
* merge handle_x2apic() into apic_id_init()
RFC:
* move out max-cpus check out of mptable_setup()
* factor out CPU counting/apic ID detection in separate function
* return back accidentially deleted debug message with APIC ID
* drop unused code in smp_setup()
According to SDM, if CPUs have APIC ID more than 254
firmware should pass control to OS in x2APIC mode.
This series adds x2APIC bootstrap initialization.
Rebased QEMU side of x2APIC support for the next merge window:
