Subject: [GIT PULL] 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


Harald Freudenberger (2):
      s390/archrandom: Rework arch random implementation.
      s390/zcrypt: Fix CCA and EP11 CPRB processing failure memory leak.

Heiko Carstens (3):
      s390/early: get rid of memmove_early
      s390/early: get rid of #ifdef CONFIG_BLK_DEV_INITRD
      s390/early: move functions which may not access bss section to extra file

Martin Schwidefsky (1):
      s390: remove closung punctuation from spectre messages

Masahiro Yamada (1):
      s390: remove no-op macro VMLINUX_SYMBOL()

Sebastian Ott (3):
      s390/cio: add helper to query utility strings per given ccw device
      s390/cio: add test for ccwgroup device
      s390/dasd: simplify locking in dasd_times_out

Thomas Richter (2):
      perf: fix invalid bit in diagnostic entry
      s390/cpum_sf: Add data entry sizes to sampling trailer entry

Ursula Braun (1):
      s390/net: add pnetid support

Vasily Gorbik (1):
      s390: introduce compile time check for empty .bss section
