# commit f89ed2f880ccb117246ba095e12087d9c3df89c5
# Merge: 0894da8 2fba357
# Author: Linus Torvalds <torvalds@linux-foundation.org>
# Date:   Tue Jul 24 10:44:24 2018 -0700
# 
#     Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
#     
#     Pull s390 fix from Martin Schwidefsky.
#     
#     Guenter Roeck reports that the s390 allmodconfig build fails because of
#     a gcc plugin problem.  The fix won't be in-tree until 4.19, so for now
#     disable the gcc plugins on s390.
