* The interrupts which are directly forwarded to the MIPS core interrupts
|

|

* the CIC are assigned interrupts 8-39. The cascade occurs on C_IRQ4
|

|
* (MSP_INT_CIC). Currently we don't really distinguish between VPE1
|
||
|
* and VPE0 (or thread contexts for that matter). Will have to fix.
|

* The PER interrupts are assigned interrupts in the range 40-71.
