    x86/apic: Get rid of the legacy irq data storage · 4ef76eb6
    Thomas Gleixner authored
    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.
