[PATCH v3 0/2] linux-user/s390x: signal with SIGFPE on compare-and-trap

[Jonathan Albrecht]

qemu-s390x signals with SIGILL on compare-and-trap instructions. This
breaks OpenJDK which expects SIGFPE in its implementation of implicit
exceptions.

This patch depends on [PATCH v6 0/2] target/s390x: Fix SIGILL and SIGFPE

20210705210434.45824-1-iii@linux.ibm.com/">https://lore.kernel.org/qemu-devel/20210705210434.45824-1-iii@linux.ibm.com/

Based-on: 20210705210434.45824-1-iii@linux.ibm.com

v1 -> v2:
- Update to latest version of '... psw.addr reporting' patch
- Rebase to master and fix conflicts in tests/tcg/s390x/Makefile.target

v2 -> v3:
- Check for non-simulated IEEE exception DXC codes explicitly when
  getting si_codes
- Ensure si_code is set in all cases
- Improve comments
