Some shell tests compete for resources and so can't run with other
tests, tag such tests. The "(exclusive)" stems from shared/exclusive
to describe how the tests run as if holding a lock.
For ARM/coresight tests:

On my system, perf list is very slow to print the whole events. I think
there's a performance issue in SDT and uprobes event listing. I noticed
this issue while running perf test on x86 but it takes long to check
some CoreSight event which should be skipped quickly.
Anyway, some test uses perf list to check whether the required event is
available before running the test. The perf list command can take an
argument to specify event class or (glob) pattern. But glob pattern is
only to suppress output for unmatched ones after checking all events.
In this case, specifying event class is better to reduce the number of
events it checks and to avoid buggy subsystems entirely.
No functional changes intended.

Running shellcheck -S on test_arm_spe.sh throws below warnings:
#shellcheck -S warning tests/shell/test_arm_spe.sh
In tests/shell/test_arm_spe.sh line 30:
trap cleanup_files exit term int
^--^ SC3049 (warning): In POSIX sh, using lower/mixed case for signal names is undefined.
^--^ SC3049 (warning): In POSIX sh, using lower/mixed case for signal names is undefined.
^-^ SC3049 (warning): In POSIX sh, using lower/mixed case for signal names is undefined.
Fixed this issue by using uppercase for "EXIT", "TERM" and
"INIT" signals to avoid using lower/mixed case for signal
names as input.

The latest version of grep claims the egrep is now obsolete so the build
now contains warnings that look like:
egrep: warning: egrep is obsolescent; using grep -E
fix this up by moving the related file to use "grep -E" instead.
sed -i "s/egrep/grep -E/g" `grep egrep -rwl tools/perf`
Here are the steps to install the latest grep:
wget http://ftp.gnu.org/gnu/grep/grep-3.8.tar.gz
tar xf grep-3.8.tar.gz
cd grep-3.8 && ./configure && make
sudo make install
export PATH=/usr/local/bin:$PATH

In the past it had a problem not setting the pid/tid on the sample
correctly when system-wide mode is used. Although it's fixed now it'd
be nice if we have a test case for it.
