The for_each_shell_test macro iterated over all shell tests in the
directory using readdir, which does not guarantee any ordering, causing
problems on certain fs. However, the order in which they are visited
determines the id of the test, in case one wants to run a single test.

This patch replaces readdir with scandir using alphabetical sorting.
This guarantees that, given the same set of tests, all machines will
see the tests in the same order, and, thus, that test ids are
consistent.

When run as normal user with default sysctl kernel.kptr_restrict=0
and kernel.perf_event_paranoid=2, perf probe fails with:

  $ ./perf probe move_page_tables
  Relocated base symbol is not found!

The warning message is not much informative. The reason perf fails
is because /proc/kallsyms is restricted by perf_event_paranoid=2
for normal user and thus perf fails to read relocated address of
the base symbol.

Tweaking kptr_restrict and perf_event_paranoid can change the
behavior of perf probe. Also, running as root or privileged user
works too. Add these details in the warning message.

Plus, kmap->ref_reloc_sym might not be always set even if
host_machine is initialized. Above is the example of the same.
Remove that comment.

The dummy event is mainly used for mmap, the TIME sample is only needed
for per-cpu case so that the perf tool can rely on the correct timing
for parsing symbols.  And the CPU sample is useless for mmap.

The BRANCH_STACK sample bit will be always reset for the dummy event in
the function evsel__config(), so don't need to repeatedly reset it for
Arm SPE specific.

So this patch only enables TIME sample for per-cpu mmap.

Now it's hard code to set sample flags for CPU, TIME and TID for SPE
event, which is pointless.

The CPU is useful for sampling only for per-mmap case, it is used to
indicate the AUX trace is associated to which CPU.

The TIME sample is not needed for AUX event, since the time for AUX
event is not really used and this time is a different thing from the
timestamp in Arm SPE trace, the timestamp tracing which is controlled
by Arm SPE's config bit.

The TID sample is not useful for AUX event.

This patch corrects the sample flags for SPE event, it only set CPU
sample bit for per-cpu mmap case.

Merge tag 'perf-tools-fixes-for-v5.13-2021-05-24' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

Pull perf tool fixes from Arnaldo Carvalho de Melo:

 - Fix 'perf script' decoding of Intel PT traces for abort handling and
   sample instruction bytes.

 - Add missing PERF_IP_FLAG_CHARS for VM-Entry and VM-Exit to Intel PT
   'perf script' decoder.

 - Fixes for the python based Intel PT trace viewer GUI.

 - Sync UAPI copies (unwire quotactl_path, some comment fixes).

 - Fix handling of missing kernel software events, such as the recently
   added 'cgroup-switches', and add the trivial glue for it in the
   tooling side, since it was added in this merge window.

 - Add missing initialization of zstd_data in 'perf buildid-list',
   detected with valgrind's memcheck.

 - Remove needless event enable/disable when all events uses BPF.

 - Fix libpfm4 support (63) test error for nested event groups.

Pull cgroup fixes from Tejun Heo:

 - "cgroup_disable=" boot param was being applied too late confusing
   some subsystems. Fix it by moving application to __setup() time.

 - Comment spelling fixes. Included here to lower the chance of trivial
   future merge conflicts.

  fixes for ordering issues on unregistration which have been exposed
  through the wider usage of devm_."

Pull perf fixes from Thomas Gleixner:
 "Two perf fixes:

   - Do not check the LBR_TOS MSR when setting up unrelated LBR MSRs as
     this can cause malfunction when TOS is not supported

   - Allocate the LBR XSAVE buffers along with the DS buffers upfront
     because allocating them when adding an event can deadlock"
