fix problems in many d_mmap routines:
...
- returned EOPNOTSUPP rather than -1.
- no check for negative offset.
many of these fix potential security problems in these drivers.
XXX XXX XXX
the d_mmap cdev routine should be changed to have a prototype like:
paddr_t (*d_mmap) __P((dev_t, off_t, int));

Changes to support fork_kthread():
...
- cpu_set_kpc() now takes void *arg third argument, passed to the
entry point.
- cpu_fork() allows parent to be non-curproc iff parent is proc0.
When forking non-curproc, assume its state has already been saved.
- Adjust various pieces of machine-dependent code to account of all of this.

PR/6311: By me... There was a bug unloading the dmamap:
...
addr = map->dm_segs[0].ds_addr & ~PGOFSET;
len = map->dm_segs[0].ds_len;
len = ((addr & PGOFSET) + len + PGOFSET) & ~PGOFSET;
addr &= ~PGOFSET;
Notice that the & ~PGOFSET in the first line should be gone. This fixes
the newfs large disk panic.

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.
