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.

The irq_domain_ops.activate() callback has no return value and no way to tell the function that the activation is early. The upcoming changes to support a reservation scheme which allows to assign interrupt vectors on x86 only when the interrupt is actually requested requires: - A return value, so activation can fail at request_irq() time - Information that the activate invocation is early, i.e. before request_irq().

Now we have dedicated asm/irqdomain.h, so move irqdomain specific code into it.

We have 3 identical copies of the ioapic domain ops for acpi, mpparse, and sfi. Have a global one in the io_apic code and be done with it. To avoid include hell in io_apic.h, create a private irqdomain header and include the generic irqdomain header from there.
