[PATCH v5.15 v2 0/4] Allow CONFIG_DEBUG_INFO_DWARF5=y + CONFIG_DEBUG_INFO_BTF=y

Hi!

Can we please pick up the essential parts of this series for 5.15? I am
particularly interested in the last patch to enable BTF + DWARF5, but
the cleanup patches before are a very reasonable choice for stable@ as
well as they simplify the pahole version calculation and allow future
BTF/pahole related patches to apply cleanly as well.

Cheers,
Matthias
