Thomas Gleixner 4ef76eb6de x86/apic: Get rid of the legacy irq data storage
Now that the legacy PIC takeover by the IOAPIC is marked accordingly the
early boot allocation of APIC data is not longer necessary. Use the regular
allocation mechansim as it is used by non legacy interrupts and fill in the
known information (vector and affinity) so the allocator reuses the vector,
This is important as the timer check might move the timer interrupt 0 back
to the PIC in case the delivery through the IOAPIC fails.
