Merge tag 'objtool-core-2020-06-01' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull objtool updates from Ingo Molnar:
"There are a lot of objtool changes in this cycle, all across the map:
- 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"
