d375edc9b5 Simplify inet alias handling code: if we're adding/removing alias which
has the same prefix as some other alias on the same interface, use
newly-added rt_addrmsg() instead of hand-rolled in_addralias_rtmsg().

This eliminates the following rtsock messages:

Pinned RTM_ADD for prefix (for alias addition).
Pinned RTM_DELETE for prefix (for alias withdrawal).

Example (got 10.0.0.1/24 on vlan4, playing with 10.0.0.2/24):

before commit, addition:

Sending both RTM_ADD/RTM_DELETE messages to rtsock is completely wrong
(and requires some hacks to keep prefix in route table on RTM_DELETE).

I've tested this change with quagga (no change) and bird (*).

bird alias handling is already broken in *BSD sysdep code, so nothing
changes here, too.

I'm going to MFC this change if there will be no complains about behavior
change.

While here, fix some style(9) bugs introduced by r260488
(pointed by glebius and bde).

4cbac30b29 Split rt_newaddrmsg_fib() into two different functions.
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.

6d40361585 The changes in r233781 attempted to make logging during a machine check
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.

5945b5f5ab Rename definition of IEEE80211_FC1_WEP to IEEE80211_FC1_PROTECTED.
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.

88c4b8d145 Use the 'Virtual Interrupt Delivery' feature of Intel VT-x if supported by
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.

50b464aa1a Remove aicasm as a build dependency. It made sense when the ahc and ahd
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
ahc/ahd drivers were included.
