This patch adds the support for testing specific implementations.
This should only be used in very specific situations.  Right now
this means specific implementations of random number generators.

As it stands we use chainiv for sync algorithms and eseqiv for
async algorithms.  However, when there is more than one CPU
chainiv forces all processing to be serialised which is usually
not what you want.  Also, the added overhead of eseqiv isn't that
great.

Therefore this patch changes the default sync geniv on SMP machines
to eseqiv.  For the odd situation where the overhead is unacceptable
then chainiv is still available as an option.

Note that on UP machines chainiv is still preferred over eseqiv
for sync algorithms.

When a sync givcipher algorithm is requested, if an async version
of the same algorithm already exists, then we will loop forever
without ever constructing the sync version based on a blkcipher.

This is because we did not include the requested type/mask when
getting a larval for the geniv algorithm that is to be constructed.

When the aes-intel module is loaded on a system that does not have the
AES instructions, it prints

    Intel AES-NI instructions are not detected.

at level KERN_ERR.  Since aes-intel is aliased to "aes" it will be tried
whenever anything uses AES and spam the console.  This doesn't match
existing practice for how to handle "no hardware" when initializing a
module, so downgrade the message to KERN_INFO.

Just started running fips cavs test vectors through an s390x system
for giggles, and discovered that I missed patching s390's arch-specific
des3 implementation w/an earlier des3 patch to permit weak keys.

This change adds the same flag tweaks as
ad79cdd7 (crypto: des3_ede - permit
weak keys unless REQ_WEAK_KEY set) for s390's des3 implementation,
yields expected test results now.

FIPS-140 requires that all random number generators implement continuous self
tests in which each extracted block of data is compared against the last block
for repetition.  The ansi_cprng implements such a test, but it would be nice if
the hw rng's did the same thing.  Obviously its not something thats always
needed, but it seems like it would be a nice feature to have on occasion. I've
written the below patch which allows individual entropy stores to be flagged as
desiring a continuous test to be run on them as is extracted.  By default this
option is off, but is enabled in the event that fips mode is selected during
bootup.

The PCAP Asic as present on EZX phones is a multi function device with
voltage regulators, ADC, touch screen controller, RTC, USB transceiver,
leds controller, and audio codec.

It has two SPI ports, typically one is connected to the application
processor and another to the baseband, this driver provides read/write
functions to its registers, irq demultiplexer and ADC
queueing/abstraction.

This chip is used on a lot of Motorola phones, it was manufactured by TI
as a custom product with the name PTWL93017, later this design evolved
into the ATLAS PMIC from Freescale (MC13783).
