    x86/ioapic: Mark legacy vectors at reallocation time · 3534be05
    Thomas Gleixner authored
    When the legacy PIC vectors are taken over by the IO APIC the current
    vector assignement code is tricked to reuse the vector by allocating the
    apic data in the early boot process. This can be avoided by marking the
    allocation as legacy PIC take over. Preparatory patch for further cleanups.
