Merge tag 's390-7.1-4' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 fixes from Alexander Gordeev:

 - Enable IOMMUFD and VFIO cdev such that PCI pass-through to
   QEMU/KVM can optionally utilize native IOMMUFD

 - With HAVE_ARCH_BUG_FORMAT enabled the BUG infrastructure might
   misinterpret flags or fault. Fix this by moving the "format"
   field emission into __BUG_ENTRY()

 - The generic version of _THIS_IP_ is known to be brittle and may
   break with current and future GCC and Clang optimizations.  Fix
   it by overriding _THIS_IP_
