d641e4b8bd - There's no need to wrap kdb_active and kdb_trap() in #ifdef KDB as 
they're always available.
- Remove unused variable. [1]
- Add a missing const.
- Sort includes.

4f69477c32 Use the PROM provided SUNW,set-trap-table to take over the trap 
table. This is required in order to set obp-control-relinquished
within the PROM, allowing to safely read the OFW translations node.
Without this, f.e. a `ofwdump -ap` triggers a fatal reset error or
worse things on machines based on USIII and beyond.
In theory this should allow to remove touching %tba in cpu_setregs(),
in practice we seem to currently face a chicken and egg problem when
doing so however.

user trap handlers.

a065785f57 Greatly improve readability of trap() by using a table to convert between 
trap types and signals to send.  Rearrange KASSERTs to better handle faults
early before curthread is setup, or in the case that it gets corrupted or
set to 0.

42ab31b72d Add a panic stack, which is used as a known good stack when there is 
something wrong with the kernel stack.
Add code to check the kernel stack pointer in various important places
and try hard not to go down in flames if its wrong.

2b14434bd9 Rename and renumber trap types to comply with the user trap types as 
specified by the sparc abi.  We use numerically higher values for all
internal kernel types.
Remove soft trap types which need to be exposed to userland.  They will
move to utrap.h.

f9d393e059 Change tf_arg to uintptr_t from void * to reflect the fact that 
non-pointer values may be passed in it.  Add appropriate casts.

The interrupt type is now passed in tf_arg instead tf_type.

Also add support for hardware watch point traps.

from the trap type.

fb7edc502f Flesh out the sparc64 port considerably. This contains: 
- mostly complete kernel pmap support, and tested but currently turned
  off userland pmap support
- low level assembly language trap, context switching and support code
- fully implemented atomic.h and supporting cpufunc.h
- some support for kernel debugging with ddb
- various header tweaks and filling out of machine dependent structures
