Set the device description after we call uart_probe(). In uart_probe()
we call device-specific probe functions, which can (and typically will)
set the device description based on low-level device probe information.
In the end we never actually used the device description that we so
carefully maintained in the PCI match table. By setting the device
description after we call uart_probe(), we'll print the more user-
friendly description by default.

Add xenhvm.ko, which can be loaded along with a !XENHVM kernel in order to
provide support for the Xen/HVM environment.
This code is compiled with XENHVM defined; since this would result in the
(no longer used) "last processed" values being included in PCPU data
structures, an additional MODXENHVM define is used to exclude those. This
allows KBI to be retained for both GENERIC and XENHVM kernel configurations
(which are not KBI compatible with each other).
This is a direct commit to stable/9, since stable/10 and HEAD have XENHVM
merged into the GENERIC kernel configuration (but the changes in stable/10

dd mrsas(4) driver from LSI official support of newer MegaRAID SAS
cards. LSI has been maintaining this driver outside of the FreeBSD
tree. It overlaps support of ThunderBolt and Invader cards that mfi(4)
supports. By default mfi(4) will attach to cards. If the tunable:
hw.mfi.mrsas_enable=1
is set then mfi(4) will not probe and attach to these newer cards and
allow mrsas(4) to attach. So by default this driver will not effect
a FreeBSD system unless mfi(4) is removed from the kernel or the
tunable is enabled.
mrsas(4) attaches disks to the CAM layer so it depends on CAM and devices
show up as /dev/daX. mfiutil(8) does not work with mrsas. The FreeBSD
version of MegaCli and StorCli from LSI do work with mrsas. It appears
that StorCli only works with mrsas. MegaCli appears to work with mfi(4)
and mrsas(4).
It would be good to add mfiutil(4) support to mrsas, emulations modes,
kernel logging, device aliases to ease the transition between mfi(4)
and mrsas(4).
Style issues should be resolved by LSI when they get committers approved.
The plan is get this driver in FreeBSD 9.3 to improve HW support.
Thanks to LSI for developing, testing and working with FreeBSD to
make this driver co-exist in FreeBSD. This improves the overall
support of MegaRAID SAS.

Only initialize some mutexes for the default VNET.
In r208160, sctp_it_ctl was made a global variable, across all VNETs.
However, sctp_init() is called for every VNET that is created. This results
in the same global mutexes which are part of sctp_it_ctl being initialized. This can result
in crashes if many jails are created.
To reproduce the problem:
(1) Take a GENERIC kernel config, and add options for: VIMAGE, WITNESS,
INVARIANTS.
(2) Run this command in a loop:
jail -l -u root -c path=/ name=foo persist vnet && jexec foo ifconfig lo0 127.0.0.1/8 && jail -r foo
(see http://lists.freebsd.org/pipermail/freebsd-current/2010-November/021280.html )
Witness will warn about the same mutex being initialized.
