Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 updates from Martin Schwidefsky:
- New entropy generation for the pseudo random number generator.
- Early boot printk output via sclp to help debug crashes on boot. This
needs to be enabled with a kernel parameter.
- Add proper no-execute support with a bit in the page table entry.
- Bug fixes and cleanups.
