The latest compiler expects slightly different function prototypes
for the ubsan helpers:
lib/ubsan.c:192:6: error: conflicting types for built-in function '__ubsan_handle_add_overflow'; expected 'void(void *, void *, void *)' [-Werror=builtin-declaration-mismatch]
192 | void __ubsan_handle_add_overflow(struct overflow_data *data,
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~
lib/ubsan.c:200:6: error: conflicting types for built-in function '__ubsan_handle_sub_overflow'; expected 'void(void *, void *, void *)' [-Werror=builtin-declaration-mismatch]
200 | void __ubsan_handle_sub_overflow(struct overflow_data *data,
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~
lib/ubsan.c:207:6: error: conflicting types for built-in function '__ubsan_handle_mul_overflow'; expected 'void(void *, void *, void *)' [-Werror=builtin-declaration-mismatch]
207 | void __ubsan_handle_mul_overflow(struct overflow_data *data,
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~
lib/ubsan.c:214:6: error: conflicting types for built-in function '__ubsan_handle_negate_overflow'; expected 'void(void *, void *)' [-Werror=builtin-declaration-mismatch]
214 | void __ubsan_handle_negate_overflow(struct overflow_data *data,
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
lib/ubsan.c:234:6: error: conflicting types for built-in function '__ubsan_handle_divrem_overflow'; expected 'void(void *, void *, void *)' [-Werror=builtin-declaration-mismatch]
234 | void __ubsan_handle_divrem_overflow(struct overflow_data *data,
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Change the Linux implementation to match these, using a local typed
pointer.

README
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.
