#     Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
#     
#     Pull s390 fixes from Martin Schwidefsky:
#     
#      - a missing -msoft-float for the compile of the kexec purgatory
#     
#      - a fix for the dasd driver to avoid the double use of a field in the
#        'struct request'
#     
#     [ That latter one is being discussed, and Christoph asked for something
#       cleaner, but for now it's a fix ]
#     
#     * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux:
#       s390/dasd: use blk_mq_rq_from_pdu for per request data
#       s390/purgatory: Fix endless interrupt loop
