Hi all,

Here's version three 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

Changes since v2 include:
  * Brought back the (unchanged) patch introducing LLVM=1 so that all
    the patches are in one place and don't end up conflicting with each
    other.
  * Added a new patch to drop the strict "FUNC" symbol type match in
    the outer loop

Cheers,

Will

    script
