Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf fixes from Ingo Molnar:
"Fixes and HW enablement patches:
- Tooling fixes, most of which are tooling header synchronization
with v5.6 changes
- Fix kprobes fallout on ARM
- Add Intel Elkhart Lake support and extend Tremont support, these
are relatively simple and should only affect those models
- Fix the AMD family 17h generic event table"
