Merge tag 's390-5.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 updates from Heiko Carstens: - fix buffer size for in-kernel disassembler for ebpf programs. - fix two memory leaks in zcrypt driver. - expose PCI device UID as index, including an indicator if the uid is unique. - remove some oprofile leftovers. - improve stack unwinder tests. - don't use gcc atomic builtins anymore, just like all other architectures. Even though I'm sure the current code is ok, I totally dislike that s390 is the only architecture being special here; especially considering that there was a lengthly discussion about this topic and the outcome was not to use the builtins. Therefore open-code atomic ops again with inline assembly and switch to gcc builtins as soon as other architectures are doing. - couple of other changes to atomic and cmpxchg, and use atomic-instrumented.h for KASAN. - separate zbus creation, registration, and scanning in our PCI code which allows for cleaner and easier handling. - a rather large change to the vfio-ap code to fix circular locking dependencies when updating crypto masks. - move QAOB handling from qdio layer down to drivers. - add CRW inject facility to common I/O layer. This adds debugs files which allow to generate artificial events from user space for testing purposes. - increase SCLP console line length from 80 to 320 characters to avoid odd wrapped lines. - add protected virtualization guest and host indication files, which indicate either that a guest is running in pv mode or if the hypervisor is capable of starting pv guests. - various other small fixes and improvements all over the place. * tag 's390-5.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (53 commits) s390/disassembler: increase ebpf disasm buffer size s390/archrandom: add parameter check for s390_arch_random_generate s390/zcrypt: fix zcard and zqueue hot-unplug memleak s390/pci: expose a PCI device's UID as its index s390/atomic,cmpxchg: always inline __xchg/__cmpxchg s390/smp: fix do_restart() prototype s390: get rid of oprofile leftovers s390/atomic,cmpxchg: make constraints work with old compilers s390/test_unwind: print test suite start/end info s390/cmpxchg: use unsigned long values instead of void pointers s390/test_unwind: add WARN if tests failed s390/test_unwind: unify error handling paths s390: update defconfigs s390/spinlock: use R constraint in inline assembly s390/atomic,cmpxchg: switch to use atomic-instrumented.h s390/cmpxchg: get rid of gcc atomic builtins s390/atomic: get rid of gcc atomic builtins s390/atomic: use proper constraints s390/atomic: move remaining inline assemblies to atomic_ops.h s390/bitops: make bitops only work on longs ...
