Since commit7b4537199a("kbuild: link symbol CRCs at final link, removing CONFIG_MODULE_REL_CRCS"), the module versioning on the (non-upstreamed-yet) kvx Linux port is broken due to unexpected padding for __crc_* symbols. The kvx GCC adds padding so u32 gets 8-byte alignment instead of 4. I do not know if this happens for upstream architectures in general, but any compiler has the freedom to insert padding for faster access. Use the inline assembler to directly specify the wanted data layout. This is how we previously did before the breakage.

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.
