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.

Say Y here if you want to show the kernel pagetable layout in a
|
|
debugfs file. This information is only useful for kernel developers
|
|
who are working in architecture specific areas of the kernel.
|
|
It is probably not a good idea to enable this feature in a production
|
|
kernel.
|
|
If in doubt, say "N"
