rS322347: apic_enumerator: only set mp_ncpus and mp_maxid at probe cpus phase

Summary

Populate the lapics arrays and call cpu_add/lapic_create in the setup
phase instead. Also store the max APIC ID found in the newly
introduced max_apic_id global variable.

This is a requirement in order to make the static arrays currently
using MAX_LAPIC_ID dynamic.

178 ↗	(On Diff #31698)	Add this to x86/include/x86_var.h ?
sys/x86/x86/mptable.c
480 ↗	(On Diff #31698)	I think that xAPIC constant should be used for mptable configs.

This revision is now accepted and ready to land.Aug 7 2017, 11:09 AM

Thanks.

sys/x86/x86/mptable.c
480 ↗	(On Diff #31698)	MAX_LAPIC_ID is set to 63 or 11 on the top of the file. I'm not sure it safe to expand it to 254 (xAPIC_MAX_APIC_ID).
