* at the start of each reg (this is matched against the interrupt map).
* The interrupt map has entries of the size (physsz + 12), the 12 being the
* size of two u_int32_t that hold the interrupt number to compare against, the
* node the map belongs to and the interrupt that the child interrupt is mapped
* to (if the map entry matches).
* The first nregs registers are checked against the map; in some cases (e.g.
* PCI), only the first must be checked.
* The mask consists of a mask wich must be and-ed to the checked physical
* address part of the ofw reg and to the interrupt number before checking
* against the map.
* regm should point to a buffer of physsz size (this is not malloc'ed because
