2fe02dea17 Changes for kernels compiled with -mrtd: 
locore.s:
- cpu_switch "returns" to proc_trampoline after cpu_fork. cpu_switch is
  called with an argument, remove it from the stack when not compiled
  with -DMRTD.
- use KENTRY instead of ENTRY for all functions called from C.
- when calling C code, don't clean up the stack when compiled with -DMRTD.
- need to split fusubail into fubail and subail, because fu and su
  take different number of arguments.

machdep.c:
- set sf_p when dumping
- new function do_softclock (that just calls softclock) because softclock
  doesn't take an argument.

mainbus.c:
- establish softclock interrupt to call do_softclock

trap.c:
- trap() and syscall() allways use std C calling conventions.
- need to split fusubail into fubail and subail, because fu and su
  take different number of arguments.
- make child_return take only one argument like the other functions
  "called" via cpu_set_kpc.

vm_machdep.c:
- set sf_p in cpu_fork.

18114765d8 Fix a bug I think I introduced long, long ago. The bug would only show 
up on systems that have Zorro I/O space allocated outside the Z2 I/O
region, and then only if kvm usage is high enough to begin allocating
pages already mapped for hardware mappings.  Found and fixed by Niklas
Hallqvist on OpenBSD.

From niklas@cvs.openbsd.org:
Yay! This fixes a bug that has been there since day one of the amiga port.
We have never protected the kvm area that maps Zorro I/O registers in the
Z2 memory space from being allocated by the kmem_* routines.  Lately kvm
usage has increased and we have needed more kvm allocated than earlier thus
this area have got allocated with random results.  Most often resulting in
MMU fault panics, but also in hangs.  This bug has stalled the amiga port
release builds for several weeks, but now I *hope* the amiga will have a
chance to be built and tested in time for 2.3.
