Clang's integrated assembler complains "invalid reassignment of non-absolute variable 'var_ddq_add'" while assembling arch/x86/crypto/aes_ctrby8_avx-x86_64.S. It was because var_ddq_add was reassigned with non-absolute values several times, which IAS did not support. We can avoid the reassignment by replacing the uses of var_ddq_add with its definitions accordingly to have compatilibility with IAS.

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.
