[PATCH 0/2] s390/bpf: Fix bpf_arch_text_poke() with new_addr == NULL again

[Ilya Leoshkevich <iii@xxxxxxxxxxxxx>]

Hi,

This series fixes a regression causing perf on s390 to trigger a kernel
panic.

Patch 1 fixes the issue, patch 2 adds a test to make sure this doesn't
happen again.

Best regards,
Ilya
