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- Remove fork_return() as it has been superseded by the MI version.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.
- remove all occurances of FLAG_XXX values and replace with CARD_TYPEP_XXX
- remove sc_flag from isic softc and replace it with sc_cardtyp
remove some left over redundant definitions from isic and i4b_l1.h
remove left over cvs id from i4b cvs repository

in stead of PCI Memory space.

we must also inform the card of this change. Otherwise the sequencer
will traverse a corrupt list of SCBS. The side effects of this problem
were unknown SCBs completing in the qoutfifo or worse yet, panics due
to sequencer interrupts that referenced what, to the kernel, were invalid
SCB ids.
