[jdk21u-dev] RFR: 8350111: [PPC] AsyncGetCallTrace crashes when called while handling SIGTRAP

Wed Jul 16 08:01:27 UTC 2025

This pull request contains a backport of commit [e4d3c97c](https://github.com/openjdk/jdk/commit/e4d3c97c0f388fc4b1684b78844f2166277ffd91) from the [openjdk/jdk](https://git.openjdk.org/jdk) repository.

The commit being backported was authored by Richard Reingruber on 27 Feb 2025 and was reviewed by Martin Doerr and Thomas Stuefe.

The backport is actually clean (besides copyright header conflict).

Risk is low because the patch is very small and affects only ppc. The code is only reached when profiling with jfr or async-profiler.
