Add the appropriate scatter/gather stubs to the avx asm. In the C code, we can now always use crypt_by_sg, since both sse and asm code now support scatter/gather. Introduce a new struct, aesni_gcm_tfm, that is initialized on startup to point to either the SSE, AVX, or AVX2 versions of the four necessary encryption/decryption routines. GENX_OPTSIZE is still checked at the start of crypt_by_sg. The total size of the data is checked, since the additional overhead is in the init function, calculating additional HashKeys.

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.
