    Pull s390 updates from Martin Schwidefsky:
     "There are a couple of new things for s390 with this merge request:
    
       - a new scheduling domain "drawer" is added to reflect the unusual
         topology found on z13 machines.  Performance tests showed up to 8
         percent gain with the additional domain.
    
       - the new crc-32 checksum crypto module uses the vector-galois-field
         multiply and sum SIMD instruction to speed up crc-32 and crc-32c.
    
       - proper __ro_after_init support, this requires RO_AFTER_INIT_DATA in
         the generic vmlinux.lds linker script definitions.
    
       - kcov instrumentation support.  A prerequisite for that is the
         inline assembly basic block cleanup, which is the reason for the
         net/iucv/iucv.c change.
    
       - support for 2GB pages is added to the hugetlbfs backend.
    
      Then there are two removals:
    
       - the oprofile hardware sampling support is dead code and is removed.
         The oprofile user space uses the perf interface nowadays.
    
       - the ETR clock synchronization is removed, this has been superseeded
         be the STP clock synchronization.  And it always has been
         "interesting" code..
    
      And the usual bug fixes and cleanups"
