Take the target reg in __cpuid_entry_get_reg() instead of a pointer to a struct cpuid_reg. When building with -fsanitize=alignment (enabled by CONFIG_UBSAN=y), some versions of gcc get tripped up on the pointer and trigger the BUILD_BUG().

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.
