This allows to attach to the children (ATA devices) even without a
driver being attached. This allows atapi-cam to do its work both

disabling interrupts before updating the saved pil in the thread.  If we
save the value first then it can be clobbered if an interrupt comes in

84c7fde72e Trust the settings programmed by the BIOS over what the $PIR says.
Specifically, if the BIOS has programmed an IRQ for a device that doesn't
match the list of valid IRQs for the link, use it anyway as some BIOSes
don't correctly list the valid IRQs in the $PIR.  Also, allow the user
to specify an IRQ that $PIR claims is invalid as an override, but emit a
warning in that case.

2326e092a7 Remove support for mixed mode altogether now that we no longer use IRQ 0

c92163dcad Move MAC check_vnode_mmap entry point out from being exclusive to
MAP_SHARED so that the entry point gets executed un-conditionally.
This may be useful for security policies which want to perform access
control checks around run-time linking.

-add the mmap(2) flags argument to the check_vnode_mmap entry point
 so that we can make access control decisions based on the type of
 mapped object.
-update any dependent API around this parameter addition such as
 function prototype modifications, entry point parameter additions
 and the inclusion of sys/mman.h header file.
-Change the MLS, BIBA and LOMAC security policies so that subject
 domination routines are not executed unless the type of mapping is
 shared. This is done to maintain compatibility between the old
 vm_mmap_vnode(9) and these policies.

3aabc15941 In ppsintr, we needed ppsdev to get to the softc and nothing else.
Save a memory dereference in the ISR by passing this in directly.
Calling pps_capture is MP safe for all other operations on struct
pps_state, so there's no need to aquire the lock before we do this,
even from a fast ISR.  Avoid dereferencing sc->ppbus until after
pps_capture is called as well.  These actions reduce somewhat the
cache effects that cause variance in interrupt times.  On an
especially slow test machine (300MHz Cyrix GXm), this reduces the
interrupt latency about about 10% (from 21us to 19us) and helps a
little with the variance (although most of the variance seems to be
caused by lots of interrupt masking).

This also happens fixes one or two of bde's style issues.

95b66e9e53 Close a race between sleepq_broadcast() and sleepq_catch_signals().
Specifically, sleepq_broadcast() uses td_slpq for its private pending
queue of threads that it is going to wake up after it takes them off the
sleep queue.  The problem is that if one of the threads is actually not
asleep yet, then we can end up with td_slpq being corrupted and/or the
thread being made runnable at the wrong time resulting in the td_sleepqueue
== NULL assertion failures occasionally reported under heavy load.

The fix is to stop being so fancy and ditch the whole pending queue bit.
Instead, sleepq_remove_thread() and sleepq_resume_thread() were merged
into one function that requires the caller to hold sched_lock.  This
fixes several places that unlocked sched_lock only to call a function
that then locked sched_lock, so even though sched_lock is now held
slightly longer, removing the extra lock acquires (1 pair instead of 3
in some cases) probably makes it an overall win if you don't include the
fact that it closes a race.  This is definitely a 5.4 candidate.
