1980405dfd Close long existed race with net.inet.ip.fw.one_pass = 0:
If packet leaves ipfw to other kernel subsystem (dummynet, netgraph, etc)
it carries pointer to matching ipfw rule. If this packet then reinjected back
to ipfw, ruleset processing starts from that rule. If rule was deleted
meanwhile, due to existed race condition panic was possible (as well as
other odd effects like parsing rules in 'reap list').

P.S. this commit changes ABI so userland ipfw related binaries should be
recompiled.

92a39a1942 1. Update the message that prints out for -U when the mtree database does
not exist to let the user know that it will be created for the next run.

2. Delete more stuff we're not going to use from the temproot prior to
creating the mtree database to dramatically reduce its size (162K -> 37K).

3. We've been deleting the zero-size files from temproot for a long time
now, so remove the spurious "-size +0" from the find command in the
comparison loop, and remove what is now a really stale comment.

898dda825c Pass the previously returned IRQ back to arm_get_next_irq() so that
the implementation can guarantee forward progress in the event of
a stuck interrupt or interrupt storm. This is especially critical
for fast interrupt handlers, as they can cause a hard hang in that
case. When first called, arm_get_next_irq() is passed -1.

af60635fab Since vn_lock() with the LK_RETRY flag never returns an error
for FreeBSD-CURRENT, the code that checked for and returned the
error was broken. Change it to check for VI_DOOMED set after
vn_lock() and return an error for that case. I believe this
should only happen for forced dismounts.

77373ed468 Add support for multiple passes of the device tree during the boot-time
probe.  The current device order is unchanged.  This commit just adds the
infrastructure and ABI changes so that it is easier to merge later changes
into 8.x.
- Driver attachments now have an associated pass level.  Attachments are
  not allowed to probe or attach to drivers until the system-wide pass level
  is >= the attachment's pass level.  By default driver attachments use the
  "last" pass level (BUS_PASS_DEFAULT).  Driver's that wish to probe during
  an earlier pass use EARLY_DRIVER_MODULE() instead of DRIVER_MODULE() which
  accepts the pass level as an additional parameter.
- A new method BUS_NEW_PASS has been added to the bus interface.  This
  method is invoked when the system-wide pass level is changed to kick off
  a rescan of the device tree so that drivers that have just been made
  "eligible" can probe and attach.
- The bus_generic_new_pass() function provides a default implementation of
  BUS_NEW_PASS().  It first allows drivers that were just made eligible for
  this pass to identify new child devices.  Then it propogates the rescan to
  child devices that already have an attached driver by invoking their
  BUS_NEW_PASS() method.  It also reprobes devices without a driver.
- BUS_PROBE_NOMATCH() is only invoked for devices that do not have
  an attached driver after being scanned during the final pass.
- The bus_set_pass() function is used during boot to raise the pass level.
  Currently it is only called once during root_bus_configure() to raise
  the pass level to BUS_PASS_DEFAULT.  This has the effect of probing all
  devices in a single pass identical to previous behavior.

7e92c698d9 Rework the _BBN handling for Host-PCI bridges. Previously we only trusted
a _BBN value of 0 if it was for the first bridge encountered since some
older systems returned _BBN of 0 for all bridges.  However, some newer
systems enumerate bridges with non-zero _BBN before bus 0 which is
perfectly valid.  Handle both cases by trusting the first bridge that has
a _BBN of 0 and falling back to reading from non-standard config registers
only for subsequent bridges with a _BBN of 0.  We also only perform this
check for segment (domain) 0.  We assume that _BBN is always correct
for segments other than 0.

ee44c932b2 When using i8254 as the only kernel timer source:
- Interpolate stat/prof clock using clkintr() in a similar fashion to
  local APIC timer, since statclock usually run slower.

- Liberate hardclockintr() from taking the burden of handling both stat
  and prof clock interrupt. Instead, send IPIs within clkintr() to handle
  those.

9df3e8cc3a Move C1E workaround into its own idle function. Previous workaround works
only during initial booting process, while there are laptops/BIOSes that
tend to act 'smarter' by force enabling C1E if the main power adapter
being pulled out, rendering previous workaround ineffective. Given the
fact that we still rely on local APIC to drive timer interrupt, this
workaround should keep all Turion (probably Phenom too) X\d+ alive whether
its on battery power or not.
