Fix a bug causing interrmittent panics in interrupt dispatch.
Use interrupt vectors for softints.
Add a new send_softint interface.
Improved D$ flushing.
Improve traptrace and other debugging enhancements.
Remove the entire idea of fasttrap interrupts since V9 traps are really cheap,
the CPUs are really fast, and the completely different trap frames would make
these handlers really difficult to implement.
pmap_changeprot() was only used by the clock and one other place; deprecate it.
probeget() and probeset() now take 64-bit addresses even in 32-bit mode so we
can probe IO locations by physical addresses.
Some pmap cleanup.
Some more copyright cleanup.
the arguments are changed so the address is first and the ASI second so we
can have the address in %o0:%o1 and not worry about unused registers.
Also a bit of copyright cleanup.
- 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.
