Merge tag 's390-7.0-2' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 fixes from Heiko Carstens:

 - Make KEXEC_SIG available again for CONFIG_MODULES=n

 - The s390 topology code used to call rebuild_sched_domains() before
   common code scheduling domains were setup. This was silently ignored
   by common code, but now results in a warning. Address by avoiding the
   early call

 - Convert debug area lock from spinlock to raw spinlock to address
   lockdep warnings

 - The recent 3490 tape device driver rework resulted in a different
   device driver name, which is visible via sysfs for user space. This
   breaks at least one user space application. Change the device driver
   name back to its old name to fix this
