[PATCH v4 00/12] livepatch-klp-build: small fixups and enhancements

[Joe Lawrence <joe.lawrence@redhat.com>]

v4:

- Rebased on 9a73f085dc91 (tip/objtool/urgent)
- Dropped elf_add_data() fix, added __clone_symbol() align fix [Josh]
- Adopted Josh's kernel version fix [Josh]
- Updated friendly msg, "foo.patch: unsupported patch to bar.c" [Josh]
- s/warn:/warning:/, trap_err -> die, and commit msg clarification on
  colorization commit [Josh]
- Use "fuzz" instead of "drift", adjust output ordering, and send patch
  cmd errors to stderr [Josh]
- Dropped ("livepatch/klp-build: don't look for changed objects in
  tools/") for now
- Added Song's Acks [Song]

v3: https://lore.kernel.org/live-patching/20260217160645.3434685-1-joe.lawrence@redhat.com/T/#t

- Added a patch to objtool ELF code to fix packed string section alignment
- Simplified the mkstemp() patch and surrounding code [Josh]
- Added patches to catch grep use, add Makefile shellcheck, and fix
  current shellcheck warnings [Josh]
- Simplified the short-circuit validation patch [Josh]
- Added a patch to fix short-circuit version mismatch
- Pretty-print output in color [Josh]
- Reduce 'patch' chatter to fuzz/offset warning during patch validation
- Prune tools/ from paths that find_objects() looks for changed objects

v2: https://lore.kernel.org/live-patching/20260204025140.2023382-1-joe.lawrence@redhat.com/

- Update patch subject prefixes accordingly [Josh]
- Added a small objtool/klp patch.  Test systems setup crazy long
  pathnames :D
- Removed patch ("limit parent .git directory search") as this version
  replaces the use of git apply --recount with patch and recountdiff.
  A side effect of this simplification was no longer needing this weird
  hack. [Josh]
- Updated the patch that handles input patches that add files to also
  support removing files, implement this by directly inspecting the
  .patch  +++ and --- header lines via two file lists [Josh]
- Implement two short-circuiting updates: validate patches for steps 1
  and 2, and allow the user to omit patches for steps 3 and 4.  This
  combines the original 'fail-fast' patch and some related notes on the
  v1 thread. [Josh]
- Since v2 replaces git apply with patch and recountdiff, there is no
  need for a -z/--fuzz argument, it comes with GNU patch for free.
