kernel test robot reported:
>> kernel/trace/trace_osnoise.c:966:3: warning: comparison of distinct
pointer types ('typeof ((interval)) *' (aka 'long long *') and
'uint64_t *' (aka 'unsigned long long *'))
[-Wcompare-distinct-pointer-types]
do_div(interval, USEC_PER_MSEC);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
include/asm-generic/div64.h:228:28: note: expanded from macro 'do_div'
(void)(((typeof((n)) *)0) == ((uint64_t *)0)); \
~~~~~~~~~~~~~~~~~~ ^ ~~~~~~~~~~~~~~~
As interval cannot be negative because sample_period >= sample_runtime,
making interval u64 on osnoise_main() is enough to fix this problem.

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.
