== Justification ==
ptrace-tm-spd-gpr in powerpc/ptrace will fail with Power8 on Bionic:
$ sudo ./ptrace-tm-spd-gpr
test: ptrace_tm_spd_gpr
tags: git_version:c186097-dirty
!! killing ptrace_tm_spd_gpr
!! child died by signal 15
failure: ptrace_tm_spd_gpr
This is due to a segmentation fault that happens on the child process
prior to setting cptr[2] = 1. This causes the parent process to wait
forever at 'while (!pptr[2])' and the test to be killed by the test
harness framework by timeout.
== Fix ==
48dc0ef (selftests/powerpc: Fix ptrace tm failure)
This patch can be cherry-picked for Bionic.
== Test ==
After the patch, the test will pass with:
$ sudo ./ptrace-tm-spd-gpr
test: ptrace_tm_spd_gpr
tags: git_version:c186097-dirty
success: ptrace_tm_spd_gpr
== Regression potential ==
None, change for the testing tool only.
