Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 updates from Martin Schwidefsky: - three merges for KVM/s390 with changes for vfio-ccw and cpacf. The patches are included in the KVM tree as well, let git sort it out. - add the new 'trng' random number generator - provide the secure key verification API for the pkey interface - introduce the z13 cpu counters to perf - add a new system call to set up the guarded storage facility - simplify TASK_SIZE and arch_get_unmapped_area - export the raw STSI data related to CPU topology to user space - ... and the usual churn of bug-fixes and cleanups. * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (74 commits) s390/crypt: use the correct module alias for paes_s390. s390/cpacf: Introduce kma instruction s390/cpacf: query instructions use unique parameters for compatibility with KMA s390/trng: Introduce s390 TRNG device driver. s390/crypto: Provide s390 specific arch random functionality. s390/crypto: Add new subfunctions to the cpacf PRNO function. s390/crypto: Renaming PPNO to PRNO. s390/pageattr: avoid unnecessary page table splitting s390/mm: simplify arch_get_unmapped_area[_topdown] s390/mm: make TASK_SIZE independent from the number of page table levels s390/gs: add regset for the guarded storage broadcast control block s390/kvm: Add use_cmma field to mm_context_t s390/kvm: Add PGSTE manipulation functions vfio: ccw: improve error handling for vfio_ccw_mdev_remove vfio: ccw: remove unnecessary NULL checks of a pointer s390/spinlock: remove compare and delay instruction s390/spinlock: use atomic primitives for spinlocks s390/cpumf: simplify detection of guest samples s390/pci: remove forward declaration s390/pci: increase the PCI_NR_FUNCTIONS default ...
