Merge tag 's390-6.5-2' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull more s390 updates from Alexander Gordeev: - Fix virtual vs physical address confusion in vmem_add_range() and vmem_remove_range() functions - Include <linux/io.h> instead of <asm/io.h> and <asm-generic/io.h> throughout s390 code - Make all PSW related defines also available for assembler files. Remove PSW_DEFAULT_KEY define from uapi for that - When adding an undefined symbol the build still succeeds, but userspace crashes trying to execute VDSO, because the symbol is not resolved. Add undefined symbols check to prevent that - Use kvmalloc_array() instead of kzalloc() for allocaton of 256k memory when executing s390 crypto adapter IOCTL - Add -fPIE flag to prevent decompressor misaligned symbol build error with clang - Use .balign instead of .align everywhere. This is a no-op for s390, but with this there no mix in using .align and .balign anymore - Filter out -mno-pic-data-is-text-relative flag when compiling kernel to prevent VDSO build error - Rework entering of DAT-on mode on CPU restart to use PSW_KERNEL_BITS mask directly - Do not retry administrative requests to some s390 crypto cards, since the firmware assumes replay attacks - Remove most of the debug code, which is build in when kernel config option CONFIG_ZCRYPT_DEBUG is enabled - Remove CONFIG_ZCRYPT_MULTIDEVNODES kernel config option and switch off the multiple devices support for the s390 zcrypt device driver - With the conversion to generic entry machine checks are accounted to the current context instead of irq time. As result, the STCKF instruction at the beginning of the machine check handler and the lowcore member are no longer required, therefore remove it - Fix various typos found with codespell - Minor cleanups to CPU-measurement Counter and Sampling Facilities code - Revert patch that removes VMEM_MAX_PHYS macro, since it causes a regression * tag 's390-6.5-2' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (25 commits) Revert "s390/mm: get rid of VMEM_MAX_PHYS macro" s390/cpum_sf: remove check on CPU being online s390/cpum_sf: handle casts consistently s390/cpum_sf: remove unnecessary debug statement s390/cpum_sf: remove parameter in call to pr_err s390/cpum_sf: simplify function setup_pmu_cpu s390/cpum_cf: remove unneeded debug statements s390/entry: remove mcck clock s390: fix various typos s390/zcrypt: remove ZCRYPT_MULTIDEVNODES kernel config option s390/zcrypt: do not retry administrative requests s390/zcrypt: cleanup some debug code s390/entry: rework entering DAT-on mode on CPU restart s390/mm: fence off VM macros from asm and linker s390: include linux/io.h instead of asm/io.h s390/ptrace: make all psw related defines also available for asm s390/ptrace: remove PSW_DEFAULT_KEY from uapi s390/vdso: filter out mno-pic-data-is-text-relative cflag s390: consistently use .balign instead of .align s390/decompressor: fix misaligned symbol build error ...
