Ravi Bangoria 290f7d8ce2 powerpc/selftests: Add selftest to test concurrent perf/ptrace events ... ptrace and perf watchpoints can't co-exists if their address range overlaps. See commit 29da4f91c0 ("powerpc/watchpoint: Don't allow concurrent perf and ptrace events") for more detail. Add selftest for the same.
