commit 331351f89c36bf7d03561a28b6f64fa10a9f6f3a upstream.

ghash is a keyed hash algorithm, thus setkey needs to be called.
Otherwise the following error occurs:
$ modprobe tcrypt mode=318 sec=1
testing speed of async ghash-generic (ghash-generic)
tcrypt: test  0 (   16 byte blocks,   16 bytes per update,   1 updates):
tcrypt: hashing failed ret=-126

<content type='text'>
The Blackfin CRC driver was removed by commit 9678a8dc53c1 ("crypto:
bfin_crc - remove blackfin CRC driver"), but it was forgotten to remove
the corresponding "hmac(crc32)" test vectors.  I see no point in keeping
them since nothing else appears to implement or use "hmac(crc32)", which
isn't an algorithm that makes sense anyway because HMAC is meant to be
used with a cryptographically secure hash function, which CRC's are not.

Thus, remove the unneeded test vectors.

<content type='text'>
In the quest to remove all stack VLA usage from the kernel[1], this
allocates the return code buffers before starting jiffie timers, rather
than using stack space for the array. Additionally cleans up some exit
paths and make sure that the num_mb module_param() is used only once
per execution to avoid possible races in the value changing.

There seems to be a cut-n-paste bug with the name of the buffer being
free'd, xoutbuf should be used instead of axbuf.

The performance of some aead tfm providers is affected by
the amount of parallelism possible with the processing.

Introduce an async aead concurrent multiple buffer
processing speed test to be able to test performance of such
tfm providers.

The multi buffer concurrent requests ahash speed test only
supported the cycles mode. Add support for the so called
jiffies mode that test performance of bytes/sec.

We only add support for digest mode at the moment.

<content type='text'>
For multiple buffers speed tests, the number of buffers, or
requests, used actually sets the level of parallelism a tfm
provider may utilize to hide latency. The existing number
(of 8) is good for some software based providers but not
enough for many HW providers with deep FIFOs.

Add a module parameter that allows setting the number of
multiple buffers/requests used, leaving the default at 8.
