Merge tag 'perf-core-2020-12-14' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf updates from Thomas Gleixner:
"Core:
- Better handling of page table leaves on archictectures which have
architectures have non-pagetable aligned huge/large pages. For such
architectures a leaf can actually be part of a larger entry.
- Prevent a deadlock vs exec_update_mutex
Architectures:
- The related updates for page size calculation of leaf entries
- The usual churn to support new CPUs
- Small fixes and improvements all over the place"
