- Speed up objtool significantly, especially when there are large number of sections
- Improve objtool's understanding of special instructions such as IRET,
to reduce the number of annotations required
- Implement 'noinstr' validation
- Do baby steps for non-x86 objtool use
- Simplify/fix retpoline decoding
- Add vmlinux validation
- Improve documentation
- Fix various bugs and apply smaller cleanups
