Merge tag 'perf-core-2020-12-14' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

torvalds · torvalds · commit 8a8ca83ec3cf · 2020-12-14T17:34:12.000-08:00
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"
