    Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
    
    Pull s390 updates from Martin Schwidefsky:
     "One additional new feature for 4.1, a new PRNG based on SHA-512 for
      the zcrypt driver.
    
      Two memory management related changes, the page table reallocation for
      KVM is removed, and with file ptes gone the encoding of page table
      entries is improved.
    
      And three bug fixes"
    
    * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux:
      s390/zcrypt: Introduce new SHA-512 based Pseudo Random Generator.
      s390/mm: change swap pte encoding and pgtable cleanup
      s390/mm: correct transfer of dirty & young bits in __pmd_to_pte
      s390/bpf: add dependency to z196 features
      s390/3215: free memory in error path
      s390/kvm: remove delayed reallocation of page tables for KVM
      kexec: allocate the kexec control page with KEXEC_CONTROL_MEMORY_GFP
