Currently, the seabios code in acpi.c and mptable.c assume the first
CountCPUs of MaxCountCPUs are on. Your patches update the reboot cpu
detection, but they don't update the reporting of online cpus in the
bios tables that are subsequently built.
I'm planing on fixing tables creation later when hot-plugging consecutive
cpus is in upstream qemu and I'll be working on nonconsecutive cpu (un)plug.
Goal of this patches is to fix hang after reboot if cpu(s) were hot-pluged.
