The 32-bit arm build system will complain:
tools/perf/util/python.c:75:28: error: field ‘sample’ has incomplete type
75 | struct perf_sample sample;
However, arm64 build system doesn't complain this.
The root cause is arm64 define "HAVE_KVM_STAT_SUPPORT := 1" in
tools/perf/arch/arm64/Makefile, but arm arch doesn't define this. This
will lead to kvm-stat.h include other header files on arm64 build
system, especially "util/sample.h" for util/python.c.
This will try to directly include "util/sample.h" for "util/python.c" to
avoid such build issue on arm platform.

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 reStructuredText 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.
