two bug fixes for 4.10-rc5
Hi Linus,
please pull from the 'for-linus' branch of
git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux.git for-linus
to receive the following updates:
Two changes, the first is a fix to add a missing memory clobber to the inline assembly to load control registers. This has not caused any issues so far, but who knows what code gcc will generate in future versions.
The second change is an update for the default configurations. This includes CONFIG_BUG_ON_DATA_CORRUPTION=y, we want this to be enabled for s390. The usual approach to debug problems on production systems is to use crash on a system dump and for us avoiding data corruptions is priority one.

s390/ctl_reg: make __ctl_load a full memory barrier
s390: update defconfigs
