Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux 

Pull more s390 updates from Martin Schwidefsky:

 - some cleanup for the hugetlbfs pte/pmd conversion functions

 - the code to check for the minimum CPU type is converted from
   assembler to C and an informational message is added in case the CPU
   is not new enough to run the kernel

 - bug fixes
