Merge tag 's390-5.6-4' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 fixes from Vasily Gorbik:
- Remove ieee_emulation_warnings sysctl which is a dead code.
- Avoid triggering rebuild of the kernel during make install.
- Enable protected virtualization guest support in default configs.
- Fix cio_ignore seq_file .next function to increase position index.
And use kobj_to_dev instead of container_of in cio code.
- Fix storage block address lists to contain absolute addresses in qdio
code.
- Few clang warnings and spelling fixes.
