/*

 * This header file contains MSI data structures and functions which are

 * only relevant for:

 *	- Interrupt core code

 *	- PCI/MSI core code

 *	- MSI interrupt domain implementations

 *	- IOMMU, low level VFIO, NTB and other justified exceptions

 *	  dealing with low level MSI details.

 *

 * Regular device drivers have no business with any of these functions and

 * especially storing MSI descriptor pointers in random code is considered

 * abuse. The only function which is relevant for drivers is msi_get_virq().
