- Switch read and write software bits for PUDs - Add missing hardware bits for PUDs and PMDs - Generate unwind information for C modules to fix GDB unwind error for vDSO functions - Create .build-id links for unstripped vDSO files to enable vDSO debugging with symbols - Use standard stack frame layout for vDSO generated stack frames to manually walk stack frames without DWARF information - Rework perf_callchain_user() and arch_stack_walk_user() functions to reduce code duplication - Skip first stack frame when walking user stack - Add basic checks to identify invalid instruction pointers when walking stack frames - Introduce and use struct stack_frame_vdso_wrapper within vDSO user wrapper code to automatically generate an asm-offset define. Also use STACK_FRAME_USER_OVERHEAD instead of STACK_FRAME_OVERHEAD to document that the code works with user space stack - Clear the backchain of the extra stack frame added by the vDSO user wrapper code. This allows the user stack walker to detect and skip the non-standard stack frame. Without this an incorrect instruction pointer would be added to stack traces. - Rewrite psw_idle() function in C to ease maintenance and further enhancements - Remove get_vtimer() function and use get_cpu_timer() instead - Mark psw variable in __load_psw_mask() as __unitialized to avoid superfluous clearing of PSW - Remove obsolete and superfluous comment about removed TIF_FPU flag - Replace memzero_explicit() and kfree() with kfree_sensitive() to fix warnings reported by Coccinelle - Wipe sensitive data and all copies of protected- or secure-keys from stack when an IOCTL fails - Both do_airq_interrupt() and do_io_interrupt() functions set CIF_NOHZ_DELAY flag. Move it in do_io_irq() to simplify the code - Provide iucv_alloc_device() and iucv_release_device() helpers, which can be used to deduplicate more or less identical IUCV device allocation and release code in four different drivers - Make use of iucv_alloc_device() and iucv_release_device() helpers to get rid of quite some code and also remove a cast to an incompatible function (clang W=1) - There is no user of iucv_root outside of the core IUCV code left. Therefore remove the EXPORT_SYMBOL - __apply_alternatives() contains a runtime check which verifies that the size of the to be patched code area is even. Convert this to a compile time check - Increase size of buffers for sending z/VM CP DIAGNOSE X'008' commands from 128 to 240 - Do not accept z/VM CP DIAGNOSE X'008' commands longer than maximally allowed - Use correct defines IPL_BP_NVME_LEN and IPL_BP0_NVME_LEN instead of IPL_BP_FCP_LEN and IPL_BP0_FCP_LEN ones to initialize NVMe reIPL block on 'scp_data' sysfs attribute update - Initialize the correct fields of the NVMe dump block, which were confused with FCP fields - Refactor macros for 'scp_data' (re-)IPL sysfs attribute to reduce code duplication - Introduce 'scp_data' sysfs attribute for dump IPL to allow tools such as dumpconf passing additional kernel command line parameters to a stand-alone dumper - Rework the CPACF query functions to use the correct RRE or RRF instruction formats and set instruction register fields correctly - Instead of calling BUG() at runtime force a link error during compile when a unsupported opcode is used with __cpacf_query() or __cpacf_check_opcode() functions - Fix a crash in ap_parse_bitmap_str() function on /sys/bus/ap/apmask or /sys/bus/ap/aqmask sysfs file update with a relative mask value - Fix "bindings complete" udev event which should be sent once all AP devices have been bound to device drivers and again when unbind/bind actions take place and all AP devices are bound again - Facility list alt_stfle_fac_list is nowhere used in the decompressor, therefore remove it there - Remove custom kprobes insn slot allocator in favour of the standard module_alloc() one, since kernel image and module areas are located within 4GB - Use kvcalloc() instead of kvmalloc_array() in zcrypt driver to avoid calling memset() with a large byte count and get rid of the sparse warning as result -----BEGIN PGP SIGNATURE----- iI0EABYIADUWIQQrtrZiYVkVzKQcYivNdxKlNrRb8AUCZkyx2BccYWdvcmRlZXZA bGludXguaWJtLmNvbQAKCRDNdxKlNrRb8PYZAP9KxEfTyUmIh61Gx8+m3BW5dy7p E2Q8yotlUpGj49ul+AD8CEAyTiWR95AlMOVZZLV/0J7XIjhALvpKAGfiJWkvXgc= =pife -----END PGP SIGNATURE----- Merge tag 's390-6.10-2' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux Pull more s390 updates from Alexander Gordeev: - Switch read and write software bits for PUDs - Add missing hardware bits for PUDs and PMDs - Generate unwind information for C modules to fix GDB unwind error for vDSO functions - Create .build-id links for unstripped vDSO files to enable vDSO debugging with symbols - Use standard stack frame layout for vDSO generated stack frames to manually walk stack frames without DWARF information - Rework perf_callchain_user() and arch_stack_walk_user() functions to reduce code duplication - Skip first stack frame when walking user stack - Add basic checks to identify invalid instruction pointers when walking stack frames - Introduce and use struct stack_frame_vdso_wrapper within vDSO user wrapper code to automatically generate an asm-offset define.
