[PATCH v2 0/4] further correct x86'es last-insn tracking

[Jan Beulich]

..., again involving corrections to common code as well.

v2: First and last patch are unchanged; the sole original middle patch
was split.

1: x86: don't needlessly override .bss
2: ELF: drop "push" parameter from obj_elf_change_section()
3: ELF: reliably invoke md_elf_section_change_hook()
4: x86: last-insn recording should be per-subsection
