Merge tag 's390-5.4-3' of git:https://git.kernel.org/pub/scm/linux/kernel/g…

…it/s390/linux

Pull s390 fixes from Vasily Gorbik:

 - defconfig updates

 - Fix build errors with CC_OPTIMIZE_FOR_SIZE due to usage of "i"
   constraint for function arguments. Two kvm changes acked-by Christian
   Borntraeger.

 - Fix -Wunused-but-set-variable warnings in mm code.

 - Avoid a constant misuse in qdio.

 - Handle a case when cpumf is temporarily unavailable.
