Default branch: MAIN

Modify *ASSERTMSG() so they are now used as variadic macros. The main goal
is to provide routines that do as KASSERT(9) says: append a message
to the panic format string when the assertion triggers, with optional
arguments.

Fix call sites to reflect the new definition.

Discussed on tech-kern@. See
http://mail-index.netbsd.org/tech-kern/2011/09/07/msg011427.html

Declare sh_flags volatile.
Without it, on ports where splhigh() is inline, the compiler will optimise
the second SOFTINT_PENDING test in softint_schedule(). A dissasembly
of softint_schedule() with and without the volatile sh_flags confirm this
on sparc.
Because of this there is a race that could lead to the softhand_t
being enqueued twice on si_q, leading to a corrupted queue and
some handler being SOFTINT_PENDING but never called.

Should fix PR kern/38637

Add MI code to support in-kernel preemption. Preemption is deferred by
one of the following:

- Holding kernel_lock (indicating that the code is not MT safe).
- Bracketing critical sections with kpreempt_disable/kpreempt_enable.
- Holding the interrupt priority level above IPL_NONE.

Statistics on kernel preemption are reported via event counters, and
where preemption is deferred for some reason, it's also reported via
lockstat. The LWP priority at which preemption is triggered is tuneable
via sysctl.

Merge scheduler changes from the vmlocking branch. All discussed on
tech-kern:

- Invert priority space so that zero is the lowest priority. Rearrange
  number and type of priority levels into bands. Add new bands like
  'kernel real time'.
- Ignore the priority level passed to tsleep. Compute priority for
  sleep dynamically.
- For SCHED_4BSD, make priority adjustment per-LWP, not per-process.

- Fix interactivity problems under high load. Beacuse soft interrupts
  are being stacked on top of regular LWPs, more often than not aston()
  was being called on a soft interrupt thread instead of a user thread,
  meaning that preemption was not happening on EOI.

- Don't use bool in a couple of data structures. Sub-word writes are not
  always atomic and may clobber other fields in the containing word.

- For SCHED_4BSD, make p_estcpu per thread (l_estcpu). Rework how the
  dynamic priority level is calculated - it's much better behaved now.

- Kill the l_usrpri/l_priority split now that priorities are no longer
  directly assigned by tsleep(). There are three fields describing LWP
  priority:

        l_priority: Dynamic priority calculated by the scheduler.
                This does not change for kernel/realtime threads,
                and always stays within the correct band. Eg for
                timeshared LWPs it never moves out of the user
                priority range. This is basically what l_usrpri
                was before.

        l_inheritedprio: Lent to the LWP due to priority inheritance
                (turnstiles).

        l_kpriority: A boolean value set true the first time an LWP
                sleeps within the kernel. This indicates that the LWP
                should get a priority boost as compensation for blocking.
                lwp_eprio() now does the equivalent of sched_kpri() if
                the flag is set. The flag is cleared in userret().

- Keep track of scheduling class (OTHER, FIFO, RR) in struct lwp, and use
  this to make decisions in a few places where we previously tested for a
  kernel thread.

- Partially fix itimers and usr/sys/intr time accounting in the presence
  of software interrupts.

- Use kthread_create() to create idle LWPs. Move priority definitions
  from the various modules into sys/param.h.

- newlwp -> lwp_create

Soft interrupt changes. This speeds up the slow mechanism quite a bit and
removes the requirement that IPL_SCHED == IPL_HIGH. On a DECstation 3100
using the slow mechanism, FTP transfers are about 7% slower than HEAD on
the few simple tests that I have done.

- Instead of using the run queues to schedule soft interrupts, poll for soft
  interrupt activity in mi_switch(). If there is a soft interrupt to run, we
  pick a new soft interrupt LWP to run in preference to checking the run
  queues.

- If a soft interrupt occurs while the CPU is running in userspace, hijack
  the user LWP in userret() to run the soft interrupt, thus avoiding context
  switches. This is OK to do, since in userret() the LWP can hold no locks.
  Soft interrupts will very rarely block in this configuration, and any
  blocking activity will be short term, so the user process will ~never be
  delayed by much. The downside to this approach is that it prevents the
  architecture from doing anything useful with real-time LWPs or kernel
  preemption, but that is not a problem is the fast path is implemented.

- Steal an idea from powerpc, and use DONETISR to set up multiple soft
  interrupt handlers for the legacy netisrs. Now schednetisr() just does
  softint_schedule() on the relevant handle.

- softint_execute: if a thread with higher priority has been interrupted,
  then yield. Need to find a way to optimise this as it currently means
  walking the list of pinned LWPs.
- Add blurb (to be edited/completed).
- Add a counter to track how often soft interrupts sleep.
- Minor cosmetic changes.

- Increase the number of thread priorities from 128 to 256. How the space
  is set up is to be revisited.
- Implement soft interrupts as kernel threads. A generic implementation
  is provided, with hooks for fast-path MD code that can run the interrupt
  threads over the top of other threads executing in the kernel.
- Split vnode::v_flag into three fields, depending on how the flag is
  locked (by the interlock, by the vnode lock, by the file system).
- Miscellaneous locking fixes and improvements.
