Convert rtllib from registering the crypt drivers against rtllib_crypt

R- prepended (R-CCMP, R-TKIP, R-WEP) so they will not clash with the

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
of private ashmem mmaps to match /dev/zero instead tmpfs.

n is the number of bytes to read, not the number of samples. So if there is
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

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"

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 NULL checks
The line6 driver checks struct field addresses for NULL where it does
not make sense to do so. The struct has already been checked for NULL
and there is no value in checking the first field's address too.

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
urbs using the same playback buffer space if they ever complete
out-of-order for some reason.

staging: line6: fix playback urb transfer buffer calculation
The playback urb transfer buffer calculation does not factor in
LINE6_ISO_PACKETS. Buffer memory is organized like this in the driver:
Buffer 0 Buffer 1 ...
[Packet 0, Packet 1, ...][Packet 0, Packet 1, ...][Packet 0, ...]
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
this fix in case the LINE6_ISO_PACKETS value is changed in the future.

net/hyperv: Fix the stop/wake queue mechanism
The ring buffer is only used to pass meta data for outbound packets. The
actual payload is accessed by DMA from the host. So the stop/wake queue
mechanism based on counting and comparing number of pages sent v.s. number
of pages in the ring buffer is wrong. Also, there is a race condition in
the stop/wake queue calls, which can stop xmit queue forever.
The new stop/wake queue mechanism is based on the actual bytes used by
outbound packets in the ring buffer. The check for number of outstanding
sends after stop queue prevents the race condition that can cause wake
queue happening earlier than stop queue.
