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
