staging:iio: Drop {mark,unmark}_in_use callbacks

These callbacks are currently used by the individual buffer implementations to
ensure that the request_update callback is not issued while the buffer is in use.
But the core already provides sufficient measures to prevent this from happening
in the first place. So it is safe to remove them.

There is one functional change due to this patch. Since the buffer is no longer
marked as in use when the chrdev is opened, it is now possible to enable the
buffer while it is opened. This did not work before, because mark_param_change

ashmem: Anonymous shared memory subsystem

The anonymous shared memory (ashmem) subsystem provides a
Unix-y,file-based shared memory interface to user-space. It
works like anonymous memory (e.g. mmapping fd=0) except if
you share the file descriptor via the usual means, you will
share the mapping. The shared memory can be accessed via both
mmap or file I/O. The backing store is a simple shmem file.

Additionally, ashmem introduces the concept of page pinning.
Pinned pages (the default) behave like any anonymous memory.
Unpinned pages are available to the kernel for eviction during
VM pressure. When repinning the pages, the return value
instructs user-space as to any eviction. In this manner,
user-space processes may implement caching and similar
resource management that efficiently integrates with kernel
memory management.

ashmem: Don't install fault handler for private mmaps.

Ashmem is used to create named private heaps. If this heap is backed
by a tmpfs file it will allocate two pages for every page touched.
In 2.6.27, the extra page would later be freed, but 2.6.29 does not
scan anonymous pages when running without swap so the memory is not
freed while the file is referenced. This change changes the behavior

enough data available we will write to the userspace buffer beyond its bounds.
Fix this by copying n bytes maximum. Also round n down to the next multiple of
the sample size, so we will only read complete samples. If the buffer is too
small to hold at least one sample return -EINVAL.

Also update the documentation of read_first_n to reflect the fact that 'n' is
supposed to be in bytes and not in samples.

staging: line6: fixed ALSA/PCM interaction

The PCM subsystem in the Line6 driver is mainly used for PCM playback and
capture by ALSA, but also has other tasks, most notably providing a
low-latency software monitor for devices which don't support hardware
monitoring (e.g., the TonePort series). This patch makes ALSA "play nicely"
with the other components, i.e., prevents it from resetting the isochronous
USB transfer while other PCM tasks (software monitoring) are running.

staging: line6: wait for urbs in snd_line6_prepare()

The .trigger() pcm callbacks are not allowed to block and cannot wait
until urbs have completed.  We need to ensure that stopping, preparing,
and then restarting a stream always works.

Currently the driver will sometimes return -EBUSY when restarting the
stream because urbs have not completed yet.  This can be triggered by
jackd from userspace.

The solution is to wait on urbs in the .prepare() pcm callback since
blocking is allowed in that callback.  This guarantees that all urbs are
quiesced and ready to be submitted when the start trigger callback is
invoked.

staging: line6: eliminate useless index_out variable

Playback urbs use the index_out counter to decide which part of the
playback buffer to use.  Since the urb already has a unique index in
range [0, LINE6_ISO_BUFFERS) there is no need to keep a separate
counter.

Use the urb index instead.  This also eliminates the possibility of two

out-of-order for some reason.

The playback urb transfer buffer calculation does not factor in

  Buffer 0                 Buffer 1                 ...

However, we're lucky that LINE6_ISO_PACKETS is currently defined as 1 so
this patch does not change any behavior.  It's still worth including
