Adding/deleting interface addresses involves access to 3 different subsystems,
int different parts of code. Each call can fail, so reporting successful
operation by rtsock in the middle of the process error-prone.
Further split routing notification API and actual rtsock calls via creating
public-available rt_addrmsg() / rt_routemsg() functions with "private"
rtsock_* backend.

These device IDs have an AR3012 bluetooth device that shows up with
bcdDevice=1 when it doesn't have the firmware loaded, and bcdDevice=2
when it's ready to speak full HCI.

if it was above 4GB. This was seen with CentOS 6.5 guests with
large RAM, since the block drivers are loaded late in the
boot sequence and end up allocating descriptor memory from
high addresses.

exception more readable. In practice they prevented all logging during
a machine check exception on at least some systems. Specifically, when
an uncorrected ECC error is detected in a DIMM on a Nehalem/Westmere
class machine, all CPUs receive a machine check exception, but only
CPUs on the same package as the memory controller for the erroring DIMM
log an error. The CPUs on the other package would complete the scan of
their machine check banks and panic before the first set of CPUs could
log an error. The end result was a clearer display during the panic
(no interleaved messages), but a crashdump without any useful info about
the error that occurred.
To handle this case, make all CPUs spin in the machine check handler
once they have completed their scan of their machine check banks until
at least one machine check error is logged. I tried using a DELAY()
instead so that the CPUs would not potentially hang forever, but that
was not reliable in testing.
While here, don't clear MCIP from MSR_MCG_STATUS before invoking panic.
Only clear it if the machine check handler does not panic and returns
to the interrupted thread.
The origin of WEP comes from IEEE Std 802.11-1997 where it defines
whether the frame body of MAC frame has been encrypted using WEP
algorithm or not.
IEEE Std. 802.11-2007 changes WEP to Protected Frame, indicates
whether the frame is protected by a cryptographic encapsulation
algorithm.

hardware. It is possible to turn this feature off and fall back to software
emulation of the APIC by setting the tunable hw.vmm.vmx.use_apic_vid to 0.
We now start handling two new types of VM-exits:
APIC-access: This is a fault-like VM-exit and is triggered when the APIC
register access is not accelerated (e.g. apic timer CCR). In response to
this we do emulate the instruction that triggered the APIC-access exit.
APIC-write: This is a trap-like VM-exit which does not require any instruction
emulation but it does require the hypervisor to emulate the access to the
specified register (e.g. icrlo register).
Introduce 'vlapic_ops' which are function pointers to vector the various
vlapic operations into processor-dependent code. The 'Virtual Interrupt
Delivery' feature installs 'ops' for setting the IRR bits in the virtual
APIC page and to return whether any interrupts are pending for this vcpu.

drivers and their firmware were under active development, but those days
have passed. The firmware now exists in pre-compiled form, no longer
dependent on it's sources or on aicasm. If you wish to rebuild the
firmware from source, the glue still exists under the 'make firmware'
target in sys/modules/aic7xxx.
This also fixes the problem introduced with r257777 et al with building
kernels the old fashioned way in sys/$arch/compile/$CONFIG when the

Keep a copy of the 'rip' and the 'exit_reason' and use that when calling
vmx_exit_trace(). This is because both the 'rip' and 'exit_reason' can
be changed by 'vmx_exit_process()' and can lead to very misleading traces.

Silencing the broken warning as done in r258139 renders the

it is better to just revert the original change altogether.
