SIMD vector extension sets require stricter alignment than native instruction sets to operate efficiently (AVX, NEON) or for some instructions to work at all (AltiVec). Provide facilities to define arbitrary alignment for lookup tables and scratch maps. By defining byte alignment with NFT_PIPAPO_ALIGN, lt_aligned and scratch_aligned pointers become available. Additional headroom is allocated, and pointers to the possibly unaligned, originally allocated areas are kept so that they can be freed.

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.
