    Linus Torvalds authored
    Pull x86 mm updates from Ingo Molnar:
     "The main changes in this cycle were:
    
       - Continued work to add support for 5-level paging provided by future
         Intel CPUs. In particular we switch the x86 GUP code to the generic
         implementation. (Kirill A. Shutemov)
    
       - Continued work to add PCID CPU support to native kernels as well.
         In this round most of the focus is on reworking/refreshing the TLB
         flush infrastructure for the upcoming PCID changes. (Andy
         Lutomirski)"
