In commit 0297cdc12a87 ("KVM: selftests: Add option to rseq test to override /dev/cpu_dma_latency"), a 'break' is missed before the option 'l' in the argument parsing loop, which leads to an unexpected core dump in atoi_paranoid(). It tries to get the latency from non-existent argument.

host$ ./rseq_test -u Random seed: 0x6b8b4567 Segmentation fault (core dumped)

Applied to kvm-x86 fixes, with a massaged shortlog. FWIW, I'm planning on sending Paolo a fixes pull request later this week, so this should make it into 6.19-rc1.
