Sorry! I've missed your mail.

There were a few smaller changes, mostly on the kunit tests side, here it is:

   - Bound lineinfo lookups to the resolved symbol's start so it stops stale annotations on __init code and __pfx_* padding
   - gen_lineinfo: handle SHT_REL .rel.debug_line (i386/arm32 modules)
   - gen_lineinfo: bias all exec sections, drop foreign DWARF sequences; cover .noinstr.text (kvm.ko)
   - __aligned(8) + static_asserts on the blob structs — fixes 32-bit layout mismatch (i386/m68k)
   - SLEB128 decoder: do the shift unsigned
   - KUnit: skip instead of fail when =m without KALLSYMS_LINEINFO_MODULES
   - KUnit: dereference_function_descriptor() for target addresses (ppc64 ELFv1/parisc)
   - KUnit: volatile accumulator in lineinfo_target_many_lines() (compilers fold it otherwise)
   - KUnit: OPTIMIZER_HIDE_VAR for the mid-function address — fixes objtool !ENDBR warning
   - KUnit: new regression tests (init-text stale annotation, 5-byte SLEB128 decode)
