Merge from stable/7, version 203948:

Upgrade to BIND 9.4-ESV. This version incorporates all bug and security
fixes since the release of 9.4.3, including the most recent -P5 security
fix detailed below.

From the README:
BIND 9.4-ESV will be supported until December 31, 2010, at
which time you will need to upgrade to the current release
of BIND.

This versions address the following vulnerabilities:

BIND 9 Cache Update from Additional Section
https://www.isc.org/advisories/CVE-2009-4022v6
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-4022
A nameserver with DNSSEC validation enabled may incorrectly add
unauthenticated records to its cache that are received during the
resolution of a recursive client query

BIND 9 DNSSEC validation code could cause bogus NXDOMAIN responses
https://www.isc.org/advisories/CVE-2010-0097
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-0097
There was an error in the DNSSEC NSEC/NSEC3 validation code that could
cause bogus NXDOMAIN responses (that is, NXDOMAIN responses for records
proven by NSEC or NSEC3 to exist) to be cached as if they had validated
correctly

These issues only affect systems with DNSSEC validation enabled.

MFC r203441:
Placate new binutils, by using 16-bit %ax instead of 32-bit %eax as an
argument for fnstsw. Explicitely specify sizes for the XMM control and
status word and X87 control and status words.

Fix a bug where MSI interrupts on x86 were always routed to APIC ID 0 rather
than the APIC ID of the boot CPU prior to SI_SUB_SMP.  This resulted in
some storage controllers not being able to enumerate attached devices when
using MSI/MSI-X interrupts.  This only affects <= 7.x, so it is a direct
commit to 7.3 rather than an MFC.

MFC 204090:
Fix mptutil's method for locating disk devices attached to a specific
mpt(4) controller.  Previously, the code assumed that multiple match
patterns provided to an XPT_DEV_MATCH request were ANDed together.
Instead, they are ORed.  Instead, to match peripherals for a specific bus,
one query needs to be performed to lookup the path ID of the bus.  A second
query can then be performed matching peripherals attached to that path.
This approach also makes the code a bit cleaner as the returned match
results do not mix buses and perphierals.

Back out r203073 due to issues recently discovered with machine check
hardware on some AMD processors that causes problems with running
FreeBSD as a guest on some virtual machine monitors.  What is believed
to be the correct fix has been committed but should receive more testing
before it becomes part of a release.
