/*
* This file hacked from pci_eb164_intr.s
*
* These functions were written by disassembling a Digital UNIX kernel's
* eb64p_intrdsabl and eb64p_intrenabl functions (because they had
* interesting names, and looked like the eb164 versions which were
* known to already work), and then playing with them to see how to call
* them correctly.
*
* It looks like the right thing to do is to call them with the interrupt
* request that you want to enable or disable (presumably in the range
* 0 -> 23, since there are 3 8-bit interrupt-enable bits in the
* interrupt mask PLD).
