Subject: [PATCH] x86, ioapic: Clean up ioapic/apic_id usage
While checking irte dump in dmesg, the print out is confused ioapic index
and real io apic id.
IOAPIC[0]: Set routing entry (1-1 -> 0x31 -> IRQ 1 Mode:0 Active:0 Dest:1)
IOAPIC[1]: Set IRTE entry (P:1 FPD:0 Dst_Mode:1 Redir_hint:1 Trig_Mode:0 Dlvry_Mode:1 Avail:0 Vector:31 Dest:00000001 SID:00FF SQ:0 SVT:1)
IOAPIC[0]: Set routing entry (1-2 -> 0x30 -> IRQ 0 Mode:0 Active:0 Dest:1)
IOAPIC[1]: Set IRTE entry (P:1 FPD:0 Dst_Mode:1 Redir_hint:1 Trig_Mode:0 Dlvry_Mode:1 Avail:0 Vector:30 Dest:00000001 SID:00FF SQ:0 SVT:1)
The system first ioapic id is 1.
While looking at the code, apic_id sometime is referred to index of ioapic, but
sometime is used for real apic id. and some even use apic for real apic id.
It is very confusing.
So try to limit apic_id to be real apic id for ioapic.
and use ioapic for ioapic index in the array.
