'domain_destroy with devices attached' case isn't yet handled, instead
code assumes that the device was already detached.
If the domain is destroyed the hardware still has access to invalid

Here is the Joerg's irq_remap_ops patchset updated for the latest -tip.
Simplified some of the naming conventions to follow the irq_remapping
terminology. There are still some if (irq_remapping_enabled) checks in
io_apic.c that I would like to roll into the new io_apic_ops. I will
look into

The files contain code mostly relevant for the Intel
implementation of interrupt remapping. Make that visible in
the file names. Also inline intr_remapping.h into
intr_remapping.c because it is only included there and the
content is very small. So there is

This patch introduces irq_remap_ops to hold implementation
specific function pointer to handle interrupt remapping. As
the first part the initialization functions for VT-d are
converted to these ops.

Convert these calls too:
* Disable of remapping hardware
* Reenable of remapping hardware
* Enable fault handling
With that all of arch/x86/kernel/apic/apic.c is converted to
use the generic intr-remapping interface.

The function to set interrupt affinity with interrupt
remapping enabled is Intel specific too. So move it to the
irq_remap_ops too.

The operation for releasing a remapping entry is iommu
specific too.

Remove the Intel specific interfaces from dmar.h and remove
asm/irq_remapping.h which is only used for io_apic.c anyway.
