| Ed found that on 32bit, boot_cpu_physical_apicid is not read right,
| when mptable is broken.
| 
| interesting, actually three path
| 1. acpi: at that time, at that time that is already read from reg.
| 2. mptable: that only read from mptable.
| 3. no madt, and no mptable, that use default apic id 0 for 64bit, -1 for 32bit
| 
| so could read that apic id for 2/3 path.
| 
| also could avoid set fixmap that lapic two times when acpi_lapic is used.
| and need to move cpu_has_apic earlier and call apic_disable()
