8b24036797 Require the machine-dependant DDB commands to be in db_machine_command_table[] 
and link it directly to db_command_table[] so that it's not necessary
to do this at runtime. Make db_machine_command_table[] const on all ports.
g/c now unneded stuff, like db_machine_commands_install(), db_machine_init()

Patch written by enami.

9f5a22b3ee New syscall entry implementation based on the Alpha version 
as hacked by mycroft.
- Use syscall_intern() to give a process a plain or fancy
  syscall based on ktrace flags.
- Avoid copying from the trapframe into a local array as much
  as possible.

Yields roughly 5% improvement on a 25MHz R3000 (DECstation 5000/200)
on a simple syscall benchmark.

There's still some work that can be done using __HAVE_MINIMAL_EMUL.

and to signal processing in ast() again.

fd0ca62926 Put signal posting back in userret() for now; for it to work 
properly, we need to make astpending a per-process variable.

Pointed out by mycroft.

2574f338e1 Remove a couple of now-unsed variables (args that are now no longer

1eb36d23fd - Make ast() loop around astpending; it's possible for a new 
AST to be posted when delivering signals, or after a process
  is preempted.
- Move all signal posting to ast().  userret() is now a one-liner.

777efd8cdc Check for ASTs in Syscall and UserGenException, too; AST processing 
must be done on *every* return to userland.

work.

f1152a965b Modeled after mycroft's changes to the Alpha port, add PROC_PC() to 
get profiling out of userret(), and move the preemption check to ast().

efa2b7073c make mbstate_t bigger (32 -> 128 bytes). 
XXX if you have libc after citrus locale import, please recompile libc,
and your applications that use mbstate_t (rather rare).  really sorry
for the mess.

e9e91a0fb5 split off thread specific stuff from struct sigacts to struct sigctx, leaving 
only signal handler array sharable between threads
move other random signal stuff from struct proc to struct sigctx

add the space used by UBC mappings to the initial PTE calculations
for pmaps that do that (mips and alpha).

1c726aab7f For MIPS software masking option, when returning to user mode apply 
the mask to all interrupts to catch changes in the mask state faster.
Does not affect platforms w/o this option enabled.

19adf5c987 Make userret() "static __inline". This lets it be inlined, even if you 
do not have the compiler inline normal functions to save space.  It helps
a bit on lmbench.
