In XAPIC mode, it's possible to tell VT-D to let interrupt in compatible format passing through. Signed-off-by: Tomasz Bursztyka <tomasz.bursztyka@linux.intel.com>

Such interrupt remapping hardware is provided through Intel VT-D
|
|
technology. It's being used, currently, only for MSI/MSI-X
|
|
multi-vector support. If you have such PCIe device requiring
|
|
multi-vector support, you will need to enable this.

If XAPIC mode is enabled, it will avoid remapping all interrupts.

This device should be initialized as soon as possible, before any

other device that would require it for MSI/MSI-X multi-vector support.
