Eric Biggers a2b1118052 crypto: xcbc - remove unnecessary alignment logic
The xcbc template is setting its alignmask to that of its underlying
'cipher'.  Yet, it doesn't care itself about how its inputs and outputs
are aligned, which is ostensibly the point of the alignmask.  Instead,
xcbc actually just uses its alignmask itself to runtime-align certain
fields in its tfm and desc contexts appropriately for its underlying
cipher.  That is almost entirely pointless too, though, since xcbc is
already using the cipher API functions that handle alignment themselves,
and few ciphers set a nonzero alignmask anyway.  Also, even without
runtime alignment, an alignment of at least 4 bytes can be guaranteed.

Thus, at best this code is optimizing for the rare case of ciphers that
set an alignmask >= 7, at the cost of hurting the common cases.

Therefore, this patch removes the manual alignment code from xcbc and
makes it stop setting an alignmask.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
