284c2b9aef Merge proc::p_mutex and proc::p_smutex into a single adaptive mutex, since 
we no longer need to guard against access from hardware interrupt handlers.

Additionally, if cloning a process with CLONE_SIGHAND, arrange to have the
child process share the parent's lock so that signal state may be kept in
sync. Partially addresses PR kern/37437.

6d70f903e6 Network protocol interrupts can now block on locks, so merge the globals 
proclist_mutex and proclist_lock into a single adaptive mutex (proc_lock).
Implications:

- Inspecting process state requires thread context, so signals can no longer
  be sent from a hardware interrupt handler. Signal activity must be
  deferred to a soft interrupt or kthread.

- As the proc state locking is simplified, it's now safe to take exit()
  and wait() out from under kernel_lock.

- The system spends less time at IPL_SCHED, and there is less lock activity.

30abe39468 - Retire SYCALL_MPSAFE. With the exceptions of darwin and irix emulations, 
all system calls are now MPSAFE.

c6186face4 Welcome to 4.99.55: 
- Add a lot of missing selinit() and seldestroy() calls.

- Merge selwakeup() and selnotify() calls into a single selnotify().

- Add an additional 'events' argument to selnotify() call.  It will
  indicate which event (POLL_IN, POLL_OUT, etc) happen.  If unknown,
  zero may be used.

Note: please pass appropriate value of 'events' where possible.
Proposed on: <tech-kern>

aa6e59f5dc A number of performance changes: 
Change internal register SSP to contain curlwp insread curcpu().  This
shrinks the GENERIC by 2KB.
Add rwlock stubs (rw_enter, rw_exit, rw_tryenter).
Simplify simple lock code for uniprocessors.
Do SPL raise/lower in cpu_handle_ipi instead of simple_locks.

49ffaced1c Fix a bug in the pmap pcb tracking code. While here, rewrite it to simplier. 
Use a field in the pcb itself (since it's basically free) and keep track of
what pmap "owns" a pcb (for consistency checking).  use M_ZERO as appropriate.

bb33f35f20 Since files.wscons et al. are included by ~all ports anyway, include 
them in the mi "files" file, and remove include statements from md files.
These shouldn't pull in additional kernel code when not in use, so it
shouldn't do any harm except a risk of namespace collisions which
should be easy to fix.

fb00b83874 Give bbusy() an interlock argument. If the we need to wait for the buffer, 
the interlock is dropped and reacquired when awoken. This allows for
busying buffers attached to a list that is not locked by bufcache_lock.
