Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 updates from Martin Schwidefsky:
- 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
