Merge tag 's390-5.1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 updates from Martin Schwidefsky: - A copy of Arnds compat wrapper generation series - Pass information about the KVM guest to the host in form the control program code and the control program version code - Map IOV resources to support PCI physical functions on s390 - Add vector load and store alignment hints to improve performance - Use the "jdd" constraint with gcc 9 to make jump labels working again - Remove amode workaround for old z/VM releases from the DCSS code - Add support for in-kernel performance measurements using the CPU measurement counter facility - Introduce a new PMU device cpum_cf_diag to capture counters and store thenn as event raw data. - Bug fixes and cleanups * tag 's390-5.1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (54 commits) Revert "s390/cpum_cf: Add kernel message exaplanations" s390/dasd: fix read device characteristic with CONFIG_VMAP_STACK=y s390/suspend: fix prefix register reset in swsusp_arch_resume s390: warn about clearing als implied facilities s390: allow overriding facilities via command line s390: clean up redundant facilities list setup s390/als: remove duplicated in-place implementation of stfle s390/cio: Use cpa range elsewhere within vfio-ccw s390/cio: Fix vfio-ccw handling of recursive TICs s390: vfio_ap: link the vfio_ap devices to the vfio_ap bus subsystem s390/cpum_cf: Handle EBUSY return code from CPU counter facility reservation s390/cpum_cf: Add kernel message exaplanations s390/cpum_cf_diag: Add support for s390 counter facility diagnostic trace s390/cpum_cf: add ctr_stcctm() function s390/cpum_cf: move common functions into a separate file s390/cpum_cf: introduce kernel_cpumcf_avail() function s390/cpu_mf: replace stcctm5() with the stcctm() function s390/cpu_mf: add store cpu counter multiple instruction support s390/cpum_cf: Add minimal in-kernel interface for counter measurements s390/cpum_cf: introduce kernel_cpumcf_alert() to obtain measurement alerts ...
