s390 patches for the 4.18 merge window
Hi Linus,
please pull from the 'for-linus' branch of
git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux.git for-linus
to receive the following updates:
- A rework for the s390 arch random code, the TRNG instruction is rather slow and should not be used on the interrupt path
- A fix for a memory leak in the zcrypt driver
- Changes to the early boot code to add a compile time check for code that may not use the .bss section, with the goal to avoid initrd corruptions
- Add an interface to get the physical network ID (pnetid), this is useful to group network devices that are attached to the same network
- Some cleanup for the linker script
- Some code improvement for the dasd driver
- Two fixes for the perf sampling support
