Subject: [PATCH v4 0/3] Fix 'faddr2line' for LLVM arm64 builds

Hi all,

Here's version four of my faddr2line fixes previously posted here:

v1: https://lore.kernel.org/r/20230724174517.15736-1-will@kernel.org
v2: https://lore.kernel.org/r/20230725211157.17031-1-will@kernel.org
v3: https://lore.kernel.org/r/20230728113415.21067-1-will@kernel.org

Changes since v3 include:
  * Add support for specifying specific LLVM versions with LLVM=
  * Drop the mksysmap filter in favour of a simpler regex implementing
    is_mapping_symbol()

Cheers,

Will
