So you pull out the compose_remapped_msi_msg() out of msi_compose_msg

Move these checks to IRQ remapping code by introducing the
panic_on_irq_remap() function.

Hi,
here is the third version of the patch-set to improve the abstraction
of interrupt remapping in the x86 core code. A more detailed description
can be found in the original post at:
https://lkml.org/lkml/2012/8/7/317
Changes from v2-v3:
* Rebased to v3.6-rc7
* Worked
The function is called unconditionally now in IO-APIC code
removing another irq_remapped() check from x86 core code.

remapping code. The irq_remapping_enabled check can be
removed from default_setup_hpet_msi.

This call-back is used to dump IO-APIC entries for debugging

IO-APIC and PIC use the same resume routines when IRQ
remapping is enabled or disabled. So it should be safe to
mask the other APICs for the IRQ-remapping-disabled case
too.

This function is only called from default_ioapic_set_affinity()
which is only used when interrupt remapping is disabled
since the introduction of the set_affinity function pointer.
So the check will always evaluate as true and can be
removed.
