2a08b0b7a1 Add a safety-belt. If the identified disk has 0 blocks, don't attach
it.  This can happen in some cases when plugging in SD/SmartCard PC
Cards with empty slots.  It is better to detect this bogosity, and
refuse to attach rather than panic with a division by zero (in one of
many places) down stream.

e987ee58d9 Allocate and setup an interrupt vector for corrected machine checks.
For now, just print when we get the interrupt, but eventually we need

b64400a03f Improve the comment and man page for vm_page_alloc(). Specifically,
document one of the optional flags; clarify which of the flags are
optional (and which are not), and remove mention of a restriction on
the reclamation of cached pages that no longer holds since version 7.

478fbccb67 This fixes a crash in SCTP. It was possible to have a
large number of packets queued to a crashing process.
In a specific case you may get 2 ABORT's back (from
say two packets in flight). If the aborts happened to
be processed at the same time its possible to have
one free the association while the other is trying
to report all the outbound packets. When this occured
it could lead to a crash.

a5548bf685 Import the Statistical Information For TCP Research (SIFTR) kernel module into
FreeBSD. SIFTR logs a range of statistics on active TCP connections to a log
file, providing the ability to make highly granular measurements of TCP
connection state. The tool is aimed at system administrators, developers and
researchers alike. Please take it for a spin and test it out - the man page
should have all the information required to get you going.

Many thanks go to the Cisco University Research Program Fund at Community
Foundation Silicon Valley and the FreeBSD Foundation. Their support of our work
at the Centre for Advanced Internet Architectures, Swinburne University of
Technology is greatly appreciated.

c9c987cd35 sh: Use $PWD instead of getcwd() for the \w and \W prompt expansions.

606c58db25 Fix a bug that WILL cause a panic. Basically
a read-lock is being called to check the vtag-timewait cache.
Then in two cases (where a vtag is bad i.e. in the time-wait
state) the write-unlock is called NOT the read-unlock. Under
conditions where lots of associations are coming and going
this will cause the system to panic at some point.

911fddbcb5 SR-IOV support added to igb
What this provides is support for the 'virtual function'
interface that a FreeBSD VM may be assigned from a host
like KVM on Linux, or newer versions of Xen with such
support.

When the guest is set up with the capability, a special
limited function 82576 PCI device is present in its virtual
PCI space, so with this driver installed in the guest that
device will be detected and function nearly like the bare
metal, as it were.

The interface is only allowed a single queue in this configuration
however initial performance tests have looked very good.

Enjoy!!

95976f3f38 Simplify entry to vm_pageout_clean(). Expect the page to be locked.
Previously, the caller unlocked the page, and vm_pageout_clean()
immediately reacquired the page lock.  Also, assert rather than test
that the page is neither busy nor held.  Since vm_pageout_clean() is
called with the object and page locked, the page can't have changed
state since the caller verified that the page is neither busy nor
held.

c5e0ba5fe4 On powerpc, calculate s_scale using the non-FP version previously
specific to hp300. Since FreeBSD does not support hp300, hp300 has
been removed from the condition altogether.

The FP version broke profiling on powerpc due to invalid results.
Casting to double instead of float resolved the issue, but with
Book-E not having a FP unit, the non-FP version looked preferrable.
Note that even on AIM hardware the FP version yielded an invalid
value for s_scale, so the problem is most likely with the compiler
or with the expression itself.
