When building the new aegis128 NEON code in big endian mode, Clang
complains about the const uint8x16_t permute vectors in the following
way:
crypto/aegis128-neon-inner.c:58:40: warning: vector initializers are not
compatible with NEON intrinsics in big endian mode
[-Wnonportable-vector-initialization]
static const uint8x16_t shift_rows = {
^
crypto/aegis128-neon-inner.c:58:40: note: consider using vld1q_u8() to
initialize a vector from memory, or vcombine_u8(vcreate_u8(), vcreate_u8())
to initialize from integer constants
Since the same issue applies to the uint8x16x4_t loads of the AES Sbox,
update those references as well. However, since GCC does not implement
the vld1q_u8_x4() intrinsic, switch from IS_ENABLED() to a preprocessor
conditional to conditionally include this code.

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.
