Linus Torvalds 2a8120d7b4 more s390 updates for 6.10 merge window
- 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
