298e3d15d7 Work around non-compliant BIOS PCI link devices. Some systems have the
following behavior:

* Link devices return invalid status (_STA) values.  The results are very
  unreliable -- sometimes never present.  Just ignore the status and pick
  the best configuration from _PRS.

* Link devices return invalid current settings (_CRS).  Even after setting
  the link value, many systems still return a different setting for _CRS.
  When setting an IRQ, don't bother to check _CRS to see if we succeeded.
  Note that we still check _CRS before routing and this should be addressed
  as well.

Since this is a sensitive area, leave the old behavior accessible via
uncommenting the define for ACPI_OLD_PCI_LINK at the top of the file.  Once
this has been thoroughly tested, this option and the code it covers will
be removed.

Thanks to Len Brown at Intel for informing us of these issues as he worked
around them in Linux.

0cafadacae Remove the attempt to cache the previous page mapped at our identity
location (for the wake code).  It should not be needed since we don't
map other pages at the same location and if there was an old mapping, it
would be restored by a fault.  The old code had serious problems, namely
that it was restoring the new page it had just removed (not opage) and
it could only guess at the right protection (since there's no
pmap_extract_protect function).  Thanks to Alan Cox for explaining much
of this to me.

Also, remove a commented-out initializecpu() call since it is not needed.
Restoring the cpu context is better than attempting to init from scratch.

d1fb385c10 Fix the startup logic for sendmail. If sendmail_enable=yes, don't start
the submit and outbound daemon, else if sendmail_submit_enable=yes, don't
start the outbound daemon.  Only one daemon should be started.

Also, do not rebuild database maps at boot time.  The code didn't pay
attention to SENDMAIL_MAP_TYPE and assumed 'hash'.  Also, admins may
not want maps automatically rebuilt just because the back end database
has changed.  Finally, some maps are built with mode tools than just
makemap (e.g., using cidrexpand on the access text file before sending
it to makemap).

2208ce0a06 Replace s_isnan.c and s_isnanf.c with the more compact s_isnan.c from

486b7efd12 ia64 specific:
o  Remove the code that creates the boot directory on the EFI file
   system after it has been mounted, as well as remove the code
   that creates the symlink from /boot -> /efi/boot (*). As a result,
   /boot will be extracted onto the root file system.
o  Add a function efi_mountpoint() that returns the mount point of
   the EFI file system or NULL if no EFI partition is created. This
   function is used to both check whether there's an EFI file system
   and to return what its mount point is.
o  When there's no EFI file system, ask the user if this is what he
   or she wants. Since we extract /boot onto the root file system,
   we do not actually need an EFI file system for the installation to
   work. Whether one wants to install without an EFI partition is
   of course an entirely different question. We allow it...
o  When we're done installing and need to fix up the various bits
   and pieces, check if there's an EFI partition and if yes, move
   /boot to /efi/boot and create a symlink /boot -> /efi/boot (*).
   This is a much more reliable way to get /boot onto the EFI
   partition than creating the symlink up front and hope its being
   respected. It so happened that we never had the boot directory
   end up on the EFI partition. We make the symlink relative.

(*) /efi is a place holder for the actual EFI mount point of course.

one CPU doing a TLB shootdown to another CPU that is doing a lazy pmap
shootdown each of which are waiting on each other.  With this change, only

6f4481422e More minor cleanups and one small bug fix:
- In ntoskrnl_var.h, I had defined compat macros for
  ntoskrnl_acquire_spinlock() and ntoskrnl_release_spinlock() but
  never used them. This is fortunate since they were stale. Fix them
  to work properly. (In Windows/x86 KeAcquireSpinLock() is a macro that
  calls KefAcquireSpinLock(), which lives in HAL.dll. To imitate this,
  ntoskrnl_acquire_spinlock() is just a macro that calls hal_lock(),
  which lives in subr_hal.o.)

- Add macros for ntoskrnl_raise_irql() and ntoskrnl_lower_irql() that
  call hal_raise_irql() and hal_lower_irql().

- Use these macros in kern_ndis.c, subr_ndis.c and subr_ntoskrnl.c.

- Along the way, I realised subr_ndis.c:ndis_lock() was not calling
  hal_lock() correctly (it was using the FASTCALL2() wrapper when
  in reality this routine is FASTCALL1()). Using the
  ntoskrnl_acquire_spinlock() fixes this. Not sure if this actually
  caused any bugs since hal_lock() would have just ignored what
  was in %edx, but it was still bogus.

This hides many of the uses of the FASTCALLx() macros which makes the
code a little cleaner. Should not have any effect on generated object
code, other than the one fix in ndis_lock().

789902c3ae Correct a very rare case where command ordering could be compromised
by a transaction performing a driver handled message sequence (an
scb with the MK_MESSAGE flag set).

SCBs that perform host managed messaging must always be
at the head of their per-target selection queue so that
the firmware knows to manually assert ATN if the current
negotiation agreement is packetized.  In the past we
guaranteed this by queuing these SCBs separarately in
the execution queue.  This exposes the system to potential
command reordering in two cases:

1) Another SCB for the same ITL nexus is queued that does
   not have the MK_MESSAGE flag set.  This SCB will be
   queued to the per-target list which can be serviced
   before the MK_MESSAGE scb that preceeded it.

2) If the target cannot accept all of the commands in the
   per-target selection queue in one selection, the remainder
   is queued to the tail of the selection queues so as to
   effect round-robin scheduling.  This could allow the
   MK_MESSAGE scb to be sent to the target before the
   requeued commands.

This commit changes the firmware policy to defer queuing
MK_MESSAGE SCBs into the selection queues until this can
be done without affecting order.  This means that the
target's selection queue is either empty, or the last
SCB on the execution queue is also a MK_MESSAGE SCB.
During any wait, the firmware halts the download of new
SCBs so only a single "holding location" is required.

Luckily, MK_MESSAGE SCBs are rare and typically occur only
during CAM's bus probe where only one command is outstanding
at a time.  However, during some recovery scenarios, the
reordering *could* occur.

aic79xx.c:
	Update ahd_search_qinfifo() and helper routines to
	search for pending MK_MESSAGE scbs and properly
	restitch the execution queue if either the MK_MESSAGE
	SCB is being aborted, or the MK_MESSAGE SCB can be
	queued due to the execution queue draining due to
	aborts.

	Enable LQOBUSFREE status to assert an interrupt.
	This should be redundant since a BUSFREE interrupt
	should always occur along with an LQOBUSFREE event,
	but on the Rev A, this doesn't seem to be guaranteed.

	When a PPR request is rejected when a previously
	existing packetized agreement is in place, assume
	that the target has been reset without our knowledge
	and revert to async/narrow transfers.  This corrects
	two issues: the stale ENATNO setting that was used
	to send the PPR is cleared so the firmware is not
	confused by a future packetized selection with
	ATN asserted but no MK_MESSAGE flag in the SCB and
	it speeds up recovery by aborting any pending
	packetized transactions that by definition are now
	dead.

	When re-queueing SCBs after a failed negotiation
	attempt, ensure command ordering by freezing the
	device queue first.

	Traverse the list of pending SCBs rather than the
	whole SCB array on the controller when pushing
	MK_MESSAGE flag changes out to the controller.
	The original code was optimized for the aic7xxx
	controllers where there are fewer controller slots
	then pending SCBs and the firmware picks SCB
	slots.  For the U320 controller, the hope is
	that we have fewer pending SCBs then the 512
	slots on the controller.

	Enhance some diagnostics.

	Factor out some common code.

aic79xx.h:
	Add prototype for new ahd_done_with_status() that is
	used to factor out some commone code.

aic79xx.reg:
	Add definisions for the pending MK_MESSAGE SCB.

aic79xx.seq:
	Defer MK_MESSAGE SCB queing to the execution queue
	so as to preserve command ordering.  Re-arrange some
	of the selection processing code so the above change
	had no performance impact on the common code path.

	Close a few critical section holes.

	When entering a non-packetized phase, manually enable
	busfree interrupts, since the controller hardware
	does not do this automatically.

aic79xx_inline.h:
	Enhance logging for queued SCBs.

aic79xx_osm.c:
	Add new a new DDB ahd command, ahd_dump, which
	invokes the ahd_dump_card_state() routine on the
	unit specified with the ahd_sunit DDB command.

aic79xx_pci.c:
	Turn on the BUSFREEREV bug for the Rev B. controller.
	This is required to close the busfree during non-packetized
	phase hole.
