scripts/faddr2line has not worked by default for arm64 since 5.17
Firstly, since commit f9b3cd245784 ("Kconfig.debug: make DEBUG_INFO selectable from a choice"), CONFIG_DEBUG_INFO was not getting enabled by default (and this is required for faddr2line to work).
Secondly, commit dcea997beed6 ("faddr2line: Fix overlapping text section failures, the sequel") caused a breakage for arm64, as reported at the following: https://lore.kernel.org/lkml/3bd9817d-1959-c081-e5d0-8b0e70b3f41e@huawei.com/
Josh has sent fixes/improvements for faddr2line at the following: https://lore.kernel.org/lkml/cover.1658426357.git.jpoimboe@kernel.org/
In this series I enable CONFIG_DEBUG_INFO by enabling CONFIG_DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT, which seems the sensible option.
As for merging this, I am not sure who would pick it up - any takers welcome.
Note: this is based on next-20220722 and it may be wiser to sync the defconfig manually (instead of using 1/2). Indeed I am not sure what is the policy is of sync'ing this anyway.
Thanks!
