MFC r330304: imcsmb(4): Intel integrated Memory Controller (iMC) SMBus
controller driver

imcsmb(4) provides smbus(4) support for the SMBus controller functionality
in the integrated Memory Controllers (iMCs) embedded in Intel Sandybridge-
Xeon, Ivybridge-Xeon, Haswell-Xeon, and Broadwell-Xeon CPUs. Each CPU
implements one or more iMCs, depending on the number of cores; each iMC
implements two SMBus controllers (iMC-SMBs).

*** IMPORTANT NOTE ***
Because motherboard firmware or the BMC might try to use the iMC-SMBs for
monitoring DIMM temperatures and/or managing an NVDIMM, the driver might
need to temporarily disable those functions, or take a hardware interlock,
before using the iMC-SMBs. Details on how to do this may vary from board to
board, and the procedure may be proprietary. It is strongly suggested that
anyone wishing to use this driver contact their motherboard vendor, and
modify the driver as described in the manual page and in the driver itself.
(For what it's worth, the driver as-is has been tested on various SuperMicro
motherboards.)

Merge driver for PMC Sierra's range of SAS/SATA HBAs.

Microsoft vmbus, storage and other related driver enhancements for HyperV.
- Vmbus multi channel support.
- Vector interrupt support.
- Signal optimization.
- Storvsc driver performance improvement.
- Scatter and gather support for storvsc driver.
- Minor bug fix for KVP driver.
Thanks royger, jhb and delphij from FreeBSD community for the reviews
and comments. Also thanks Hovy Xu from NetApp for the contributions to
the storvsc driver.

Add VirtIO console driver.

Revert changes to shared code of the ixl and ixlv drivers to allow
for easier long-term maintainability.

Restrict the drivers to building on amd64 for now as it is
only tested on that 64bit architecture.

Just depend on PCI and neither INET nor INET6; also make sure we
can build individual drivers and they do not depend on each other
anymore.

entropy from hypervisors.

entry to bhyve guests.

In kernel config files, it is supposed to be 'options<space><tab>' not
'options<tab><tab>', per long standing (but recently not so strictly
enforced) convention.

MFC 264304: Really only allow IMGACT_BINMISC for amd64/i386 builds.

Merge r256868,257276-257277,257515,257913 from head. These are fixes
required to make Xen buтldable w/o INET.
