[PATCHv2 bpf 0/2] bpf: Fix prog_array_map_poke_run map poke update

[Jiri Olsa <jolsa@kernel.org>]

hi,
this patchset fixes the issue reported in [0].

For the actual fix in patch 2 I'm changing bpf_arch_text_poke to allow to skip
ip address check in patch 1. I considered adding separate function for that,
but because each arch implementation is bit different, adding extra arg seemed
like better option.

v2 changes:
  - make it work for other archs

thanks,
jirka
