2220907b6e Introduce a temporary mutex, mac_ifnet_mtx, to lock MAC labels on
network interfaces.  This global mutex will protect all ifnet labels.
Acquire the mutex across various MAC activities on interfaces, such
as security checks, propagating interface labels to mbufs generated
from the interface, retrieving and setting the interface label.

Introduce mpo_copy_ifnet_label MAC policy entry point to copy the
value of an interface label from one label to another.  Use this
to avoid performing a label externalize while holding mac_ifnet_mtx;
copy the label to a temporary ifnet label and then externalize that.

Implement mpo_copy_ifnet_label for various MAC policies that
implement interface labeling using generic label copying routines.

a82b25f9b2 Better OFW console support on Sun Ultra2 machines.
Ultra2 users may want to set OFWCONS_POLL_HZ to a value of '20'.
I have left default value at '4' as higher values can consume a more
than is acceptable amount of CPU, and we don't have a consensus yet
what is an optimal value.

d7af790b0d Currently, if the drives specified for volume creation are
not active GEOM providers, it will result in a kernel panic.

If the GEOM provider or disk goes away before the volume
configuration data gets written to the disk, it will result
in another kernel panic.

o Make sure that the drives specified for volume creation
  are active GEOM providers.

o When writing out volume configuration data to associated drives,
  make sure that the GEOM provider is active, otherwise continue
  to the next drive in the volume.

3f11a2f374 Introduce sbreserve_locked(), which asserts the socket buffer lock on
the socket buffer having its limits adjusted.  sbreserve() now acquires
the lock before calling sbreserve_locked().  In soreserve(), acquire
socket buffer locks across read-modify-writes of socket buffer fields,
and calls into sbreserve/sbrelease; make sure to acquire in keeping
with the socket buffer lock order.  In tcp_mss(), acquire the socket
buffer lock in the calling context so that we have atomic read-modify
-write on buffer sizes.

80f0e4c265 Run the power off code directly instead of using indirection through
smp_rendezvous() to ensure we run on the BSP.  This reverts rev 1.128.
Add a comment indicating that MI code should be the one that runs all
shutdown functions on the BSP with the APs halted.  This should work
around problems in power off while waiting for the MI code to be improved.

cc822cb53e Make uma_mtx MTX_RECURSE. Here's why:
The general UMA lock is a recursion-allowed lock because
there is a code path where, while we're still configured
to use startup_alloc() for backend page allocations, we
may end up in uma_reclaim() which calls zone_foreach(zone_drain),
which grabs uma_mtx, only to later call into startup_alloc()
because while freeing we needed to allocate a bucket.  Since
startup_alloc() also takes uma_mtx, we need to be able to
recurse on it.

This exact explanation also added as comment above mtx_init().

6d90faf3d8 Add support for TCP Selective Acknowledgements. The work for this
originated on RELENG_4 and was ported to -CURRENT.

The scoreboarding code was obtained from OpenBSD, and many
of the remaining changes were inspired by OpenBSD, but not
taken directly from there.

You can enable/disable sack using net.inet.tcp.do_sack. You can
also limit the number of sack holes that all senders can have in
the scoreboard with net.inet.tcp.sackhole_limit.

2fc3727323 Finally implement bus_config_intr() support for I/O APIC interrupt sources.
This should fix problems with older SMP systems that only have ISA/EISA
IRQs when routing virgin PCI interrupts as well as on other boxes whose
MADT does not have any interrupt override entries for ISA IRQs that are
used to route PCI interrupts even in APIC mode.

95957f6256 - Defer BUS_CONFIG_INTR() on ACPI IRQ resources until the resources are
actually used.  For most ACPI devices this means deferring the call
  until bus_alloc_resource().
  - Add a function acpi_config_intr() to call BUS_CONFIG_INTR() for an
    ACPI IRQ resource using the trigger mode and polarity information
    stored in the ACPI resource object.
  - Add a function acpi_lookup_irq_resource() to lookup the ACPI IRQ
    resource that corresponds to a specified rid and new-bus resource.
  - Have the ACPI PCI bridge driver call BUS_CONFIG_INTR() on interrupts
    that it routes through link devices.
- Remove needactivate variable from acpi_alloc_resource() by changing the
  function not modify the flags variable but just mask off RF_ACTIVE when
  calling rman_reserve_resource().

96d3b93753 Various cleanups in support of a future ioapic_config_intr() function:
- Allow ioapic_set_{nmi,smi,extint}() to be called multiple times on the
  same pin so long as the pin's mode is the same as the mode being
  requested.
- Add a notion of bus type for the interrupt associated with interrupt pin.
  This is needed so that we can force all EISA interrupts to be active high
  in the forthcoming ioapic_config_intr().
- Fix a bug for EISA systems that didn't remap IRQs.  This would have broken
  EISA systems that tried to disable mixed mode for IRQ 0.
