staging: unisys: fix random hangs with network stress in visornic

We learned that it was possible for the core networking code to call
visornic_xmit() within ISR context, resulting in the need for us to
use spin_lock_irqsave() / spin_lock_irqrestore() to lock accesses to our
virtual device channels.

Without the correct locking added in this patch, random hangs would occur
on typical kernels while stressing the netork.  When using a kernel with
CONFIG_DEBUG_SPINLOCK=y, a stackdump would occur at the time of the hang
reporting:

    BUG: spinlock recursion on CPU#0, vnic_incoming/<pid>

(see below for more details)

We considered the possibility of adding a protocol between a visordriver
and visorbus where the visordriver could specify which type of locking it
required for its virtual device channels (essentially indicating whether
or not it was possible for the channel to be accessed in ISR context), but
decided this extra complexity was NOT needed, and that channel queues
should always be accessed with the most-stringent locking.  So that is
what is implemented in this commit.

Below is an example stackdump illustrating the spinlock recursion that is
fixed by this commit.  Note that we are first in virtnic_rx() writing to
the device channel when an APIC timer interrupt occurs.  Within the core
networking code, net_rx_action() calls process_backlog(), which eventually
lands up back up in virtnic_xmit() in the code attempting to also write to
the device channel.

visorchannel_write() and it's user visorbus_write_channel() are
exported, so all visorbus function drivers (i.e., drivers that call
visorbus_register_visor_driver()) are potentially affected by the bug.

Because of pointer-arithmetic rules, the address being written to in the
affected code was actually at byte offset:

    sizeof(struct channel_header) * offset

instead of just <offset> bytes as intended.

The bug could cause some very difficult-to-diagnose symptoms.  The
particular problem that led me on this chase was a kernel fault that
would occur during 'insmod visornic' after a previous 'rmmod visornic',
where we would fault during netdev_register_kobject() within
pm_runtime_set_memalloc_noio() while traversing a device list, which
occurred because dev->parent for the visorbus device had become

visornic_remove() is called to logically detach the visornic driver from a
visorbus-supplied device, which can happen either just prior to a

this removal, which was fixed via the following changes:

* A going_away flag is now used to interlock between device destruction and
  workqueue operations, protected by priv_lock.  I.e., setting
  going_away=true under lock guarantees that no new work items can get
  queued to the work queues.  going_away=true also short-circuits other
  operations to enable device destruction to proceed.

* Missing clean-up operations for the workqueues, netdev, debugfs entries,
  and the worker thread were added.

* Memory referenced from the visornic private devdata struct is now freed

staging: unisys: add error messages to visornic

Add error message to genuine rare error paths, and debug messages
to enable relatively non-verbose tracing of code paths

You can enable debug messages by including this on the kernel command line:

    visornic.dyndbg=+p

or by this from the command line:

    echo "module visornic +p" > <debugfs>/dynamic_debug/control

Refer to Documentation/dynamic-debug-howto.txt for more details.

In addition to the new debug and error messages, a message like the
following will be logged every time a visornic device is probed, which
will enable you to map back-and-forth between visorbus device names
(e.g., "vbus2:dev0") and netdev names (e.g., "eth0"):

    visornic vbus2:dev0: visornic_probe success netdev=eth0

With this patch and visornic debugging enabled, you should expect to see
messages like the following in the most-common scenarios:

* driver loaded:

      visornic_init

* device probed:

      visornic vbus2:dev0: visornic_probe
      visor_thread_start
      visor_thread_start success

* network interface configured (ifconfig):

      net eth0: visornic_open

Fix problem that prevents us from responding to any device message after
device_create.

By neglecting to NULL out pending_msg_hdr after the device_create response,
we were effectively preventing any subsequent messages to the device from
working, because device_epilog() will correctly bail out early if it sees
that pending_msg_hdr is still set non-NULL, as that is an indicator to mean
that an unanswered message is still outstanding.

This problem was discovered as part of testing IOVM service partition
recovery, because device_epilog() was in fact bailing out when it was
called from my_device_changestate(), which of course prevented us from
transitioning the device to the paused state.  However, the incorrect
behavior would occur for ANY subsequent command directed at the device,
not just for changestate.

staging: comedi: use CAP_SYS_ADMIN instead of CAP_NET_ADMIN

If the "comedi" module has been loaded with the
"comedi_num_legacy_minors" module parameter set to a non-zero value,
some reserved comedi devices get created.  These can be attached to a
low-level comedi driver using the `COMEDI_DEVCONFIG` ioctl command,
which checks for the `CAP_SYS_ADMIN` capability.  Of course, the comedi
device needs to be opened before the ioctl command can be sent.  If the
comedi device is unattached, `comedi_open()` currently requires the
`CAP_NET_ADMIN` capability.  It makes more sense to just require the
`CAP_SYS_ADMIN` capability here, so change it.

For the curious, commit a8f80e8ff94e ("Networking: use CAP_NET_ADMIN
when deciding to call request_module") changed this capability from
`CAP_SYS_MODULE` to `CAP_NET_ADMIN`, even though it doesn't seem
relevant here.  The original `CAP_SYS_MODULE` capability was due to the
function having some code to request a module using a "char-major-%i-%i"
alias, but that was never compiled in and was removed by commit
f30f2c2d417b ("staging: comedi: remove check for CONFIG_KMOD").

staging: comedi: cb_pcimdas: add external analog output ranges

The analog output range is not programmable, but the ranges for each of
the two analog output channels are settable via jumpers.  These jumper
settings are not readable by the driver.  The driver
provides a range table containing all the possible internal ranges
(+/-10V, +/-5V, 0-10V, 0-5V) to provide information to the user
application (although any range selected by the application that differs
from the jumper settings will not produce the expected voltage output).

The range table does not cover all possible ranges of the analog output
channels.  The jumpers also allow an external reference voltage between
0 and 10V to be used as bipolar or unipolar output range.  Add a couple
more ranges to the end of the range table to define these two external
ranges.
