Pull s390 fixes from Martin Schwidefsky:
 "Another two bug fixes for 4.7:

   - The revert of patch which removed boot information for systems
     using an intermediate boot kernel, e.g. the SLES12 grub setup.

   - A fix for an incorrect inline assembly constraint that causes
     broken code to be generated with gcc 4.8.5"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux:
  s390: fix test_fp_ctl inline assembly contraints
