a2c86ff9f2 Don't remove the first mbuf in the chain if it got empty.
This removes the packet header in certain cases which later on
will give panic. Clarify what the atm_intr expects in the comment
and de-obscurify the code a little bit by replacing the portability
macros with the BSD names. The code isn't maintained externally anymore
so there's no point in keeping the extra level of obscurity.

3325da8ccd Improve the SIOCSIFCAP handler a bit:
- allow for ifp->if_ioctl being NULL, as the rest of ifioctl() does;
- give the interface driver a chance to report a error to the caller;
- don't forget to update ifp->if_lastchange upon successful modification
  of interface operation parameters.

a0f2609521 Tidy up the thread taskqueue implementation and close a lost wakeup race.
Instead of creating a mutex that we msleep on but don't actually lock when
doing the corresponding wakeup(), in the kthread, lock the mutex associated
with our taskqueue and msleep while the queue is empty.  Assert that the
queue is locked when the callback function is called to wake the kthread.

00e521cd6b - call ip6_output() instead of nd6_output() when ipsec tunnel
mode is applied, since tunneled packets are considered to be
  generated packets from a tunnel encapsulating node.
- tunnel mode may not be applied if SA mode is ANY and policy
  does not say "tunnel it".  check if we have extra IPv6 header
  on the packet after ipsec6_output_tunnel() and call ip6_output()
  only if additional IPv6 header is added.
- free the copyed packet before returning.

01946bf901 Added sysctl security.jail.jailed.
It returns 1 is process is inside of jail and 0 if it is not.
Information if we are in jail or not is not a secret, there is plenty of
ways to discover it. Many people are using own hack to check this and
this will be a legal way from now on.

It will be great if our starting scripts will take advantage of this sysctl
to allow clean "boot" inside jail.

1dc86cc4a5 Switch to using the new $PIR interrupt routing code and remove the old

87d8124455 Rework the $PIR (aka PCIBIOS) PCI interrupt routing code and split it off
into its own file:
- All of the $PIR interrupt routing is now done in a link-centric fashion.
  When a host-PCI bridge that uses the $PIR attaches, it calls pir_parse()
  to parse the table.  This scans for link devices and merges all the masks
  for each link device from the table entries.  It then looks at the intline
  register of PCI devices connected to a link to figure out if the BIOS has
  routed this link and if so to which IRQ.
- The IRQ for any given link can be overridden via a hint like so:
  'hw.pci.link.0x62.irq=10'  Any IRQ set in this matter is treated as if it
  were set that way by the BIOS.
- We only call the BIOS to route each link device once.
- When a PCI device wants to route an interrupt, we look it up in the $PIR
  to find the associated link.  If the link is routed, we simply return the
  IRQ it is using.  If it is not routed, we have to pick one.  This uses a
  different algorithm from the old code.  First off, when we try to pick
  an interrupt from a mask of possible interrupts, we try to pick the one
  that is least loaded as far as PCI devices.  We maintain this weight based
  on the number of devices attached to each link device.  When choosing an
  IRQ, we first attempt to route using any PCI only interrupts (the old
  code did this as well).  If that doesn't work, we try to use the list of
  IRQs that the BIOS has used.  This is a new step that the new code didn't
  do and avoids using IRQ 3 or 4 for every virgin interrupt routing.  If
  none of the IRQs that the BIOS used worked, then we fall back to trying
  anything.
- The fallback mask for !PC98 was fixed to include IRQ 3 and not allow IRQ
  2.
- We don't use the $PIR to route interrupts on a PCI-PCI bridge unless it
  has already been used to route on at least one Host-PCI bridge.  This
  helps to avoid mixing and matching x86 firmware PCI interrupt routing
  methods (which is a Bad Thing(tm)).

49c92e5706 Change the disk(9) API in order to make device removal more robust.
Previously the "struct disk" were owned by the device driver and this
gave us problems when the device disappared and the users of that device
were not immediately disappearing.

Now the struct disk is allocate with a new call, disk_alloc() and owned
by geom_disk and just abandonned by the device driver when disk_create()
is called.

Unfortunately, this results in a ton of "s/\./->/" changes to device
drivers.

Since I'm doing the sweep anyway, a couple of other API improvements
have been carried out at the same time:

The Giant awareness flag has been flipped from DISKFLAG_NOGIANT to
DISKFLAG_NEEDSGIANT

A version number have been added to disk_create() so that we can detect,
report and ignore binary drivers with old ABI in the future.

Manual page update to follow shortly.
