The signal context structure pointer is always saved at the base

of the frame which "calls" the signal handler. We only want to find

the hardware save state structure, which lives 10 32bit words into

sigcontext structure.

At one time we peeked at %r31 rather than the PC queues to determine

what instruction took the fault. This was done on purpose, but I don't

| 56 |
|

remember why. Looking at the PC queues is really the right way, and
|
| 57 |
|
|
I don't remember why that didn't work when this code was originally

| 58 |
|

written. */
