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 * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: s390/zcrypt: Fix CCA and EP11 CPRB processing failure memory leak. s390/archrandom: Rework arch random implementation. s390/net: add pnetid support s390/dasd: simplify locking in dasd_times_out s390/cio: add test for ccwgroup device s390/cio: add helper to query utility strings per given ccw device s390: remove no-op macro VMLINUX_SYMBOL() s390: remove closung punctuation from spectre messages s390: introduce compile time check for empty .bss section s390/early: move functions which may not access bss section to extra file s390/early: get rid of #ifdef CONFIG_BLK_DEV_INITRD s390/early: get rid of memmove_early s390/cpum_sf: Add data entry sizes to sampling trailer entry perf: fix invalid bit in diagnostic entry
