- Add kselftest for damos_apply_interval_us sysfs file
- Rebase on latest mm-unstable
DAMON-based operation schemes are applied for every aggregation
interval. That is mainly because schemes are using nr_access
Update DAMON selftests to test existence of the file for reading/writing
DAMOS apply interval under each scheme directory.

Fix three issues with resctrl selftests.

Currently, _GNU_SOURCE is defined in resctrl.h. Defining _GNU_SOURCE

It is safer to define _GNU_SOURC

Smatch complains that the missing error checks would lead to a crash:
lib/kunit/executor_test.c:40 parse_filter_test()
error: double free of 'filter.test_glob'
We may as well do it right...

Create selftests for PCIe BW control through the PCIe cooling device

First, the BW control selftest finds the PCIe port to test with. By
default, the PCIe port with the highest bus speed is selected but
another PCIe port can be provided with -d parameter.

In intel_pstate_tracer.py, Gnuplot is used to generate 2D plots.
In current implementation this tracer gives error while importing
the module because Gnuplot is imported from package Gnuplot-py which
does not support python 3.x. Fix this by using pygnuplot package to
import this module.

In selftests/amd-pstate, tbench and gitsource microbenchmarks are used to
compare the performance with different governors. In Current

Also selftests/amd-pstate uses distro `perf` to capture stats

Yes... b
kselftests fails to build because the mm/testcases subdirectory is not
created and then the compiler fails to output the binary there.
So fix this by simply removing this subdirectory which is not very
useful.
