With the upcoming reservation/management scheme, early activation will assign a special vector. The final activation at request_irq() assigns a real vector, which needs to be updated in the tables. Split out the reconfiguration code in set_affinity and use it for reactivation.

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().

BIOS can set up x2apic_opt_out bit on some platforms, for various misguided reasons like insane SMM code with weird assumptions about what descriptors look like, or wanting Windows not to enable the IOMMU so that the graphics driver will take it over for SVM in "driver mode". A user can either disable the x2apic_opt_out bit in BIOS or by kernel parameter "no_x2apic_optout". Instead of printing a warning, we just print information of x2apic opt out.
