0767992461 If we don't explicitly recognise the trap type, only panic if it 
came from kernel mode. Otherwise, print details of the exception
and send a SIGILL to the process.

The is necessary now that debug exceptions are handled here.

4a06119a9d Pass the system call table to trace_enter() and ktrsys() so that it is 
possible to use alternate system call tables. This is usefull for
displaying correctly the arguments in Mach binaries traces.

If NULL is given, then the regular systam call table for the process is used.

57c2c2b87f Add a hack at the end of setregs() which works around a bug which can, 
under some circumstances, leave turds in the icache following vmspace
teardown.

It's not yet clear if this is a pmap bug or a toolchain problem since
the hack is unecessary when the kernel is compiled with -O0. Of course
that could just be masking the problem due to increased icache pressure...

a3885e9bdd - Change VM_MIN_KERNEL_ADDRESS to start at KSEG1 instead of KSEG0. 
- Overhaul the TLB management code such that we now keep track of
   the exact TLB slot at which a mapping was inserted, both for user-
   space and kernel mappings. This addresses #2 on the TODO list.

d584ed9598 Add a realcode argument to trace_enter and ktrsyscall. realcode is the 
original system call number, which can be negative for a Mach trap.
We cannot just replace code by realcode, because ktrsyscall uses it as
an index in the system call table, thus crashing the kernel when the
value is negative.

3795c4e6f4 Since we keep a list of all mappings for a given physical page (even 
unmanaged mappings) so we can deal with cache aliases, make sure to
skip unmanaged/wired mappings (added via pmap_kenter_pa()) when doing
things like pmap_page_protect().

c82ab2eb79 now that mem_no is emitted by config(8), there is no reason to keep 
copy of more or less identical iskmemdev() for every arch; move the function

e0cc03a09b merge kqueue branch into -current 
kqueue provides a stateful and efficient event notification framework
currently supported events include socket, file, directory, fifo,
pipe, tty and device changes, and monitoring of processes and signals

kqueue is supported by all writable filesystems in NetBSD tree
(with exception of Coda) and all device drivers supporting poll(2)

based on work done by Jonathan Lemon for FreeBSD
initial NetBSD port done by Luke Mewburn and Jason Thorpe

8496cdaeb7 - Fix REDUCE16 to ignore the upper 32-bits of the input operand.

  in the "ldlo.q" instruction. (And remove the "XXX:" comment which correctly
  hinted that this might be necessary).
