Bug description:
[Impact]
The powerpc tests from kernel selftests were unable to finish properly
on Power10 VM with Focal 5.4 kernel. There will be lots of failures for
powerpc/ptrace and powerpc/tm tests. For example the ptrace-tm-gpr:
# selftests: powerpc/ptrace: ptrace-tm-gpr
# test: ptrace_tm_gpr
# tags: git_version:unknown
# [FAIL] Test FAILED on line 94
# GPR[14]: 1 Expected: 2

[Fix]
* 031fd80f87 selftests: Skip TM tests on synthetic TM implementations
This patch has already landed on Jammy+. Only Focal will need this
patch. And it needs to be backported to skip changes on the
tm-signal-pagefault.c test, which does not exist on Focal tree.
[Test Plan]
Run the patched powerpc tests from kernel selftests:
$ sudo make TARGETS=powerpc run_tests
Previously failing powerpc/ptrace and powerpc/tm tests will be skipped.
For example the ptrace-tm-gpr test:
# selftests: powerpc/ptrace: ptrace-tm-gpr
# test: ptrace_tm_gpr
# tags: git_version:b315960-dirty
# [SKIP] Test skipped on line 116
# skip: ptrace_tm_gpr
ok 2 selftests: powerpc/ptrace: ptrace-tm-gpr
[Where problems could occur]
Change limited to testing tools, and it's just skipping unsuitable
tests for specific architecture, no impact to real kernel functions.
== Original Bug Report ==
First time seen on cycle 2023.08.10 because it was the first time we tested
this instance.
Tried previous focal version (5.4.09-156) and it seems it's happened before.
The following tests are failing:
* powerpc/ptrace:ptrace-tm-gpr FAIL
* powerpc/ptrace:ptrace-tm-spd-gpr FAIL
* powerpc/ptrace:ptrace-tm-tar timeout
* powerpc/ptrace:ptrace-tm-spd-tar timeout
* powerpc/ptrace:ptrace-tm-vsx timeout
* powerpc/ptrace:ptrace-tm-spd-vsx timeout
* powerpc/ptrace:ptrace-tm-spr timeout
