e62be0bfe7 - Proc locking.
- P_OWEUPC -> PS_OWEUPC.

a92ac5b9ae - Change userret() to take a struct trapframe * as its second argument and
to extract the PC from that to send to addupc_task() so that it can be
  called from MI code.
- Remove all traces of have_giant with extreme prejudice and use
  mtx_owned(&Giant) instead where appropriate.
- Proc locking.
- P_FOO -> PS_FOO.
- Don't grab Giant just to look in curproc's p_addr during a trap since we
  may choose to immediately exit.  Instead, delay grabbing Giant a bit
  until we actually need it.
- Don't reset 'p' to 'curproc' in syscall() to handle the case of a child
  returning from fork1() since children don't return via syscall().
- Remove an XXX comment in ast() that questions the correctness of the
  userland check.  The code is correct.

0a8ec7a3bd - Proc locking.
- Don't send IPIs for pmap_invalidate_page() or pmap_invalidate_all()
  in the UP case.
- Catch up to cpuno -> cpuid.
- Convert some sanity checks that were #ifdef DIAGNOSTIC to KASSERT()'s.

21f31719b6 - Adjust some whitespace to reduce diffs with the i386 version.
- Rename the per-CPU variable 'cpuno' to 'cpuid'.  This was done so that
  there is one consistent name across all architectures for a logical
  CPU id.
- Remove all traces of IRQ forwarding.
- Add globaldata_register() hook called by globaldata_init() to register
  globaldata structures in the cpuid_to_globaldata array.
- Catch up to P_FOO -> PS_FOO.
- Bring across some fixes for forwarded_statclock() from the i386 version
  to handle ithreads and idleproc properly.
- Rename addugd_intr_forwarded() to addupc_intr_forwarded() so that it is
  the same name on all architectures.
- Set flags in p_sflag instead of calling psignal() from
  forward_hardclock().
- Proc locking.
- When we handle an IPI, turn off its bit in the mask of IPI's we are
  currently handling so that an IPI doesn't send a CPU into an infinite
  loop.

caf46c8d44 - Initialize curproc, proc0.p_heldmtx, and proc0.p_contested earlier so
that mutex operations work.
- Enter Giant earlier so we hold it during boot.
- Proc locking.
- Move globaldata_init() into here from mp_machdep.c so that UP kernels
  don't depend on mp_machdep.c.  Use a callout in the SMP case to register
  the boot processor's globaldata in the cpuid_to_globaldata array.

625c76db3a - Kill the have_giant parameter to userret() along with all instances of
that name as a variable.  Use mtx_owned(&Giant) where appropriate
  instead.
- Proc locking.
- P_FOO -> PS_FOO.
- Update comments about enable interrupts during trap and why this may be
  bad if we trap while holding a spin mutex.
- Don't bother resetting p to curproc in syscall() in case we are the child
  returning from fork.  The child hasn't returned from fork through syscall
  in a while.
- Remove fork_return() as it has been superseded by the MI version.

4cbdef8448 - Relocate portions of this file to get it into an order closer to that of
the alpha mp_machdep.c.
- Proc locking.
- Catch up to the P_FOO -> PS_FOO proc flags changes.
- Stick ap_init()'s prototype with the other prototypes.
- Remove the Xforwardirq IPI.
- Remove unused simplelocks.
- Don't try to psignal() from forward_statclock(), but set the appropriate
  signal pending flag in p_sflag instead.
- Add in KTR_SMP tracepoints for various SMP functions.   (Brought over
  from the alpha port)

52070bf2e6 - Proc locking.
- Setup proc0.p_heldmtx, proc0.contested, and curproc earlier so that we
  can use mutexes.
- Initialize sched_lock and Giant earlier and enter Giant during init386.
- Use suser(9) instead of checking cr_uid directly.

7eea49bf11 - Split p_flag up into two fields. p_flag keeps most of the previous flags
and is protected by the proc lock.  p_sflag is protected by sched_lock
  and holds the following flags: PS_INMEM, PS_OWEUPC, PS_PROFIL, PS_SINTR,
  PS_TIMEOUT, PS_ALRMPEND, PS_PROFPEND, PS_CVWAITQ, PS_SWAPINREQ, and
  PS_SWAPPING.
- p_klist is definitely locked now by the proc lock.
- p_runtime, p_[usi]u are locked by sched_lock.
- Add a new P_KTHREAD flag set for kernel threads created via
  kthread_create(9).
- STOPEVENT() only needs the proc lock, it does not need Giant.
- faultin() already checks PS_INMEM, so simplify the check in PHOLD() so
  that we only need to grab the proc lock and let faultin() perform the
  PS_INMEM check.
- Add a prototype for zpfind().
- Add prototypes for the new fork_exit() and fork_return() MI functions
  that manage the fork return path.
- Add a prototype for the MD function userret() so that it can be called
  from fork_return().
- Add needed include of <machine/frame.h> in the kernel.

5c9a541b66 Minor fixes:
- Use "OPOST | ONLCR" as a c_oflag in the raw mode instead of 0, which should
  make debug output mode readable;
- flush input buffer when switching to/from raw mode. This should prevent
  leaking raw scancodes into your shell prompt when program called
  VGLKeyboardEnd() w/o processing all scancodes in the buffer.

0d6d6aa373 Don't grab Giant when calling kmem_alloc/kmem_free as this is just
encouraging other people to follow the same practice.  If this is going
to be done, then it should be done inside of those two functions instead.
