[PATCH 0/5] Allow CONFIG_DEBUG_INFO_DWARF5=y + CONFIG_DEBUG_INFO_BTF=y

[maennich]

From: Matthias Maennich <maennich@xxxxxxxxxx>

Can we please pick this series up 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. I intentionally kept the config
PAHOLE_HAS_BTF_TAG and hence its patch complete, even though there is no
user for it.

Cheers,
Matthias
