Dedicate a pair of entry points to handling sun4m level 15 (NMI) interrupts.
...
Hardware NMIs are generated on various fault conditions that take place
asynchronously to the instruction stream. Software NMIs are going to be used
for inter-processor communications.
Get synchronous fault information separately from asynchronous fault
information. Do the former right after taking a memory fault trap and
store the values in temporary locations within the cpuinfo structure (XXX),
so we can unconditionally clear the sync fault status register after
MMU probe operations. This all is to work around a Hypersparc feature
which could lead to loss of fault information because of the fault
status register getting locked.
