Subject: [PATCH 0/2] s390: Improve handling for stack register corruption
Date: Fri, 2 Oct 2026 17:20:53 +0200 [thread overview]
Message-ID: <20261002152055.3305184-1-hca@linux.ibm.com> (raw)
Two small improvements:
- Copy last breaking event address to correct pt_regs location
- Save lowcore on invalid kernel stack to have more accurate data for
crash dump analysis
Thanks,
Heiko
