Linus Torvalds 8a8ca83ec3 Perf updates:
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
