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


Harald Freudenberger (2):
s390/archrandom: Rework arch random implementation.
