- * This is a special interrupt allocation routine called from the PHB's MSI
- * setup function. When capi interrupts are allocated in this manner they must
- * still be associated with a running context, but since the MSI APIs have no
- * way to specify this we use the default context associated with the device.
- *
- * The Mellanox CX4 has a hardware limitation that restricts the maximum AFU
- * interrupt number, so in order to overcome this their driver informs us of
- * the restriction by setting the maximum interrupts per context, and we
- * allocate additional contexts as necessary so that we can keep the AFU
- * interrupt number within the supported range.
