commit 6bee835dd54e279f3d3ae2eca92a9c394b4fd028 upstream.
Move mic/mpssd examples to samples and remove it from Documentation
Makefile. Create a new Makefile to build mic/mpssd. It can be built
from top level directory or from mic/mpssd directory:
Run make -C samples/mic/mpssd or cd samples/mic/mpssd; make

[backported to 4.4-stable as this code is broken on newer versions of
gcc and we don't want to break the build for a Documentation sample.

The following was seen in linux-next build coverage, which is somewhat
unique since it uses powerpc host to cross compile x86:

make[5]: *** [Documentation/mic/mpssd/mpssd.o] Error 1
Since it is building /usr/sbin/mpssd and /usr/sbin/micctrl
for x86_64 and the original authors indicated[1] that:
MIC card is expected to work with x86_64 host, not with ppc64.
We have never compiled on ppc host..
so it probably makes sense to just skip building these userspace
programs when we are cross compiling.

mic/mpssd along with MIC drivers are currently only usable on
x86_64. So build mic/mpssd only for x86_64 to avoid build breaks on
big-endian systems.

sysfs.c includes mpssd.h which includes virtio_ids.h.
sysfs.c doesn't have the proper include flags set to use the latest
headers, so this causes a build error if the system headers are too old.

This patch introduces a sample user space daemon which
implements the virtio device backends on the host. The daemon
creates/removes/configures virtio device backends by communicating with
the Intel MIC Host Driver. The virtio devices currently supported are
virtio net, virtio console and virtio block. Virtio net supports TSO/GSO.
The daemon also monitors card shutdown status and takes appropriate actions
like killing the virtio backends and resetting the card upon card shutdown
and crashes.
