staging: unisys: visornic_resume needs to mirror _serverdown_complete
Previously we simplified the serverdown function to basically turn it
into a dev_close(), but missed the analogous logic in visornic_resume()
(which is essentially the "book-end" of visornic_serverdown_complete()).
As a result, during IO partition recovery, the nic would go closed when
the IO partition went away, but would never be opened again when the IO
partition came back.
This patch changes visornic_resume() to use dev_open(), so that it once
again plays nicely with visornic_serverdown_complete(). Because
dev_open() forces us into the visornic_open() path, other logic in
visornic_resume() was no longer necessary, and lended to simplifying
visornic_resume() even more.

libnvdimm: fix namespace seed creation
A new BLK namespace "seed" device is created whenever the current seed
is successfully probed. However, if that namespace is assigned to a BTT
it may never directly experience a successful probe as it is a
subordinate device to a BTT configuration.
The effect of the current code is that no new namespaces can be
instantiated, after the seed namespace, to consume available BLK DPA
capacity. Fix this by treating a successful BTT probe event as a
successful probe event for the backing namespace.

driver staging area. This module is part of the MOST driver and handles
user space interaction by means of ALSA devices.
This patch is needed in order to have access to MOST synchronous data
through ALSA devices.

Staging: most: add MOST driver's core module
This patch adds the core module of the MOST driver to the kernel's driver
staging area. This module is part of the MOST driver and handles the
configuration interface in sysfs, the buffer management and the data
routing.
MOST defines the protocol, hardware and software layers necessary to allow
for the efficient and low-cost transport of control, real-time and packet
data using a single medium (physical layer). Media currently in use are
fiber optics, unshielded twisted pair cables (UTP) and coax cables. MOST
also supports various speed grades up to 150 Mbps.
For more information on MOST, visit the MOST Cooperation website:
www.mostcooperation.com.
Cars continue to evolve into sophisticated consumer electronics platforms,
increasing the demand for reliable and simple solutions to support audio,
video and data communications. MOST can be used to connect multiple
consumer devices via optical or electrical physical layers directly to one
another or in a network configuration. As a synchronous network, MOST
provides excellent Quality of Service and seamless connectivity for
audio/video streaming. Therefore, the driver perfectly fits to the mission
of Automotive Grade Linux to create open source software solutions for
automotive applications.
The driver consists basically of three layers. The hardware layer, the
core layer and the application layer. The core layer consists of the core
module only. This module handles the communication flow through all three
layers, the configuration of the driver, the configuration interface
representation in sysfs, and the buffer management.
For each of the other two layers a selection of modules is provided. These
modules can arbitrarily be combined to meet the needs of the desired
system architecture. A module of the hardware layer is referred to as an
HDM (hardware dependent module). Each module of this layer handles exactly
one of the peripheral interfaces of a network interface controller (e.g.
USB, MediaLB, I2C). A module of the application layer is referred to as an
AIM (application interfacing module). The modules of this layer give access
to MOST via one the following ways: character devices, ALSA, Networking or
V4L2.
To physically access MOST, an Intelligent Network Interface Controller
(INIC) is needed. For more information on available controllers visit:

After IO partition recovery, it was possible to get into a situation where
a visornic device would repeatedly report:
NETDEV WATCHDOG: eth0 (): transmit queue 0 timed out
The actual problem would affect any visornic device that was rapidly
transmitting at the same time the IO partition was being recovered. Once
you hit the problem, the only way to resume use of the nic would be to
reboot the Linux client partition.
The problem was caused by chstat.sent_xmit and chstat.got_xmit_done NOT
getting cleared during IO partition recovery. This is necessary because
outstanding xmits would essentially be "abandoned" during such recovery.
These fields are now cleared in virtnic_serverdown_complete().

Logic to check for failures of visorchannel_signalinsert() and
visorchannel_signalremove() were added, and a new sent_post_failed counter
tracks the number of times we failed to post a rcv buffer to the IO
partition.

staging: unisys: visornic - ensure proper net locking in tx reset logic
visornic tx reset handling is done asynchronously via a workqueue in
visornic_timeout_reset(). As a result, it needs to use rtnl_lock() /
rtnl_unlock() to lock against possible simultaneous close() of the network
device.
(I consulted the bnx2 driver as a model here, as that driver also does
its tx reset handling asynchronously, just like visornic does. See
bnx2_tx_timeout() and bnx2_reset_task().)

staging: unisys: Process more than one response per check
When s-Par is in polling mode it checks every 2 ms to see if there is
a response from the IO service partition in the queue. Currently it
just reads one entry per 2 ms, this needs to be changed so it drains
the queue on each check.
