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. 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

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, and stack frame walking would be continued with a more or
