Merge tag 's390-7.0-3' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 fixes from Vasily Gorbik:

 - Fix guest pfault init to pass a physical address to DIAG 0x258,
   restoring pfault interrupts and avoiding vCPU stalls during host
   page-in

 - Fix kexec/kdump hangs with stack protector by marking
   s390_reset_system() __no_stack_protector; set_prefix(0) switches
   lowcore and the canary no longer matches

 - Fix idle/vtime cputime accounting (idle-exit ordering, vtimer
   double-forwarding) and small cleanups
