Many cipher implementations use 4-byte/8-byte loads/stores which require
alignment on some architectures. This patch explicitly sets the alignment
requirements for them.

The cipher code path may allocate up to two blocks of data on the stack.
Therefore we need to place limits on the maximum block size.

This patch avoids shifting the count left and right needlessly for each
call to sha1_update(). It instead can be done only once at the end in
sha1_final().
Keeping the previous test example (sha1_update() successively called with
len=64), a 1.3% performance increase can be observed on i386, or 0.2% on
ARM. The generated code is also smaller on ARM.

The current code unconditionally copy the first block for every call to
sha1_update(). This can be avoided if there is no pending partial block.
This is always the case on the first call to sha1_update() (if the length
is >= 64 of course.
Furthermore, temp does need to be called if sha_transform is never invoked.
Also consolidate the sha_transform calls into one to reduce code size.

As the Crypto API now allows multiple implementations to be registered
for the same algorithm, we no longer have to play tricks with Kconfig
to select the right AES implementation.
This patch sets the driver name and priority for all the AES
implementations and removes the Kconfig conditions on the C implementation
for AES.
Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
This is the first step on the road towards asynchronous support in
the Crypto API. It adds support for having multiple crypto_alg objects
for the same algorithm registered in the system.
For example, each device driver would register a crypto_alg object
for each algorithm that it supports. While at the same time the
user may load software implementations of those same algorithms.
Users of the Crypto API may then select a specific implementation
by name, or choose any implementation for a given algorithm with
the highest priority.
The priority field is a 32-bit signed integer. In future it will be
possible to modify it from user-space.
This also provides a solution to the problem of selecting amongst
various AES implementations, that is, aes vs. aes-i586 vs. aes-padlock.

A lot of crypto code needs to read/write a 32-bit/64-bit words in a
specific gender. Many of them open code them by reading/writing one
byte at a time. This patch converts all the applicable usages over
to use the standard byte order macros.
This is based on a previous patch by Denis Vlasenko.

- Check capabilities for audio settings (volume, balance,
bass, treble, loudness, mute)
- added loudness support
- added missing VIDEO_AUDIO_BALANCE flags for v4l1 compatibility
- do not call msp_any_detect_stereo for non-autoselect chips to
retrieve the current stereo setting: that will temporarily mute
the sound. It is only needed when the stereo mode might be
changed, and for autoselect msp processors that do not periodically
need to update their stereo setting.
- do not wake up the thread if the standard did not change. Prevents
temporary audio drop-out if the standard is set to the same value.
- fix confused stereo detect code where V4L2_TUNER_SUB_STEREO and
V4L2_TUNER_MODE_STEREO values were used incorrectly.
- stereo mode reporting was broken (v4l2 value used to index a
string array expecting v4l1 mode values).
