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
