- Add a globaldata_register() prototype in the SMP case.

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.

- 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.

- 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.

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.

- Catch up to cpuno -> cpuid change.
- Add parens around a subexpression to quiet a warning.

- P_OWEUPC -> PS_OWEUPC.
- Remove obsolete prototype for MD fork_return().
|

- Add fork_exit.

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.

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)

- 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.

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.
