ebc610e5bc [CRYPTO] templates: Pass type/mask when creating instances
This patch passes the type/mask along when constructing instances of
templates.  This is in preparation for templates that may support
multiple types of instances depending on what is requested.  For example,
the planned software async crypto driver will use this construct.

For the moment this allows us to check whether the instance constructed
is of the correct type and avoid returning success if the type does not
match.

fb469840b8 [CRYPTO] all: Check for usage in hard IRQ context
Using blkcipher/hash crypto operations in hard IRQ context can lead
to random memory corruption due to the reuse of kmap_atomic slots.
Since crypto operations were never meant to be used in hard IRQ
contexts, this patch checks for such usage and returns an error
before kmap_atomic is performed.

333b0d7eea [CRYPTO] xcbc: New algorithm
This is core code of XCBC.

XCBC is an algorithm that forms a MAC algorithm out of a cipher algorithm.
For example, AES-XCBC-MAC is a MAC algorithm based on the AES cipher
algorithm.
