[PATCH] x86_64: Don't assume BSP has ID 0 in new smp bootup
This patch removes the assumption that LAPIC entries contain the BSP as its
first entry. This is a slight improvement to the temporary fix submitted by
Suresh Siddha.
- Removes assumption that LAPIC entries contain BSP first.
- Builds x86_acpiid_to_apicid[] and bios_cpu_apicid[] properly with BSP as
first entry.
- Made maxcpus=1 boot on these systems. Since the parsing earlier in
arch/x86_64/kernel/mpparse.c stopped after maxcpus entries, other entries
were not processed, this causes kernel not to boot on these systems.
TBD: x86_acpiid_to_apicid and bios_cpu_apicid[] seem to be exactly the
same. This could be removed, but might need more work to cleanup.
