    Linus Torvalds authored
    Pull second set of s390 patches from Martin Schwidefsky:
     "The second part of Heikos uaccess rework, the page table walker for
      uaccess is now a thing of the past (yay!)
    
      The code change to fix the theoretical TLB flush problem allows us to
      add a TLB flush optimization for zEC12, this machine has new
      instructions that allow to do CPU local TLB flushes for single pages
      and for all pages of a specific address space.
    
      Plus the usual bug fixing and some more cleanup"
