This module is built whenever CONFIG_COMEDI is enabled but it is
only used by the pcmmio and pcmuio drivers. The pcm_common module
consists of one exported function. Put a local copy of the function
in the pcmmio and pcmuio drivers.
This removes the need for the pcm_common module and the now unused
pcm_common.[ch] files can be deleted and removed from the Makefile.

When setting up asynchronous commands on the special interrupt
subdevice, support the `TRIG_COUNT` stop source to allow the command to
stop automatically after a specified number of scans.

Initialize the special interrupt subdevice as a digital input subdevice
even if the interrupt handler cannot be registered. It's `insn_bits`
handler will still read the interrupt status register. This hardware
status bits in this register might be valid even if they haven't been
enabled in the interrupt control register, but this needs to be checked.
In any case, initializing the subdevice as a digital input subdevice is
harmless.

staging: comedi: addi_apci_2032: use channel list
When setting up asynchronous commands for the special interrupt
subdevice, use the channel list to decide which interrupt sources to
enable. Set the maximum length of the channel list to be the same as
the number of channels (2). Normally, the channel list would include
channel 0, channel 1 or both.
When reading the scan data in the interrupt routine, the readings from
each channel in the channel list will be packed into a single unsigned
short data value. Make each bit in this value correspond to an index in
the channel list.
Since all the channels in the channel list are read at the same time,
insist that the scan end argument is the length of the channel list and
that the conversion source is `TRIG_NOW`.
Allocate some private data for the special interrupt subdevice to hold a
spin-lock, the channels to be enabled and an indication of whether the
command is still active. Stop the command if a buffer overflow occurs.

staging: comedi: addi_apci_2032: only disable triggered interrupts
The interrupt handler disables all interrupt sources when a valid
interrupt occurs. Just disable the triggered interrupt source so we can
still get interrupts for the other interrupt source.
Also add a comment indicating why the triggered interrupt source is
disabled. The interrupt sources are level-sensitive and indicate
hardware errors that are likely to be persistent, so if we reenabled
them they would just keep triggering repeatedly.

staging: comedi: addi_apci_2032: make insn_bits read live data
The `insn_bits` handler for the special digital input subdevice used for
interrupts currently uses `s->state` for the data value, which is set to
the value of the APCI2032_INT_STATUS_REG register when a valid interrupt
occurs. Just read the live register contents in the `insn_bits` handler
instead of relying on the interrupt service routine to read it for us.
The register contains a couple of hardware error status bits. They
might also be valid even when the corresponding bits have not been
enabled in the APCI_INT_CTRL_REG register in which case this would be
useful for checking for hardware errors without using interrupts, but
this needs to be checked.

Put the hardware into a safe state before enabling the interrupt. In
the interrupt routine, check the device has been fully configured by
checking `dev->attached`. In particular, `dev->read_subdev` could be
NULL early on and although the hardware's status register should
indicate no interrupt has occurred (since it's been put into a safe
state), it's better not to rely on it.

staging: usbip: userspace: add option to turn fortify on or off
This comes handy when hacking with different cross
compilers, some of which may or may not have
_FORTIFY_SOURCE turned on by default. This patch
allows us to turn _FORTIFY_SOURCE on by specifying
--with-fortify option at configuration time (or
to turn it off by specifying --without-fortify).
If nothing is specified, default compiler behavior
is assumed.
USBIP daemon relies on functions available in glib2 library
to spawn handler code for incoming connection. This makes the
whole program dependent on glib2 library, which is a GNOME library
that on systems that don't have GNOME results in pulling more
dependency, only to be able to run a relatively trivial
socket-based program.
While this may not seem to be a problem on full-blown desktops
that already have the necessary libraries, it is a big issue
on small embedded systems (think USB hub with an Ethernet port)
that only have bare essentials in their file systems.
This patch eliminates glib2 dependency by reworking the
code to use lower level system calls to dispatch connection
handler. Instead of using glib2-style event loop and dispatching
mechanism, just do a ppoll(2) system call in our own loop and call
accept(2) followed by fork(2) on the socket that has incoming
connection. Stevens' books taught us that more than twenty
years ago. No need for anything smarter in a simple server, such
as usbipd.
