Merge tag 's390-6.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 updates from Vasily Gorbik:

- Remove restrictions on PAI NNPA and crypto counters, enabling
concurrent per-task and system-wide sampling and counting events

- Switch to GENERIC_CPU_DEVICES by setting up the CPU present mask in
the architecture code and letting the generic code handle CPU
bring-up

- Add support for the diag204 busy indication facility to prevent
undesirable blocking during hypervisor logical CPU utilization
queries. Implement results caching

- Improve the handling of Store Data SCLP events by suppressing
unnecessary warning, preventing buffer release in I/O during
failures, and adding timeout handling for Store Data requests to
address potential firmware issues

- Provide optimized __arch_hweight*() implementations

- Remove the unnecessary CPU KOBJ_CHANGE uevents generated during
topology updates, as they are unused and also not present on other
architectures

- Cleanup atomic_ops, optimize __atomic_set() for small values and
__atomic_cmpxchg_bool() for compilers supporting flag output
constraint

- Couple of cleanups for KVM:
- Move and improve KVM struct definitions for DAT tables from
gaccess.c to a new header
- Pass the asce as parameter to sie64a()

- Make the crdte() and cspg() page table handling wrappers return a
boolean to indicate success, like the other existing "compare and
swap" wrappers

- Add documentation for HWCAP flags

- Switch to obtaining total RAM pages from memblock instead of
totalram_pages() during mm init, to ensure correct calculation of
zero page size, when defer_init is enabled

- Refactor lowcore access and switch to using the get_lowcore()
function instead of the S390_lowcore macro

- Cleanups for PG_arch_1 and folio handling in UV and hugetlb code

- Add missing MODULE_DESCRIPTION() macros

- Fix VM_FAULT_HWPOISON handling in do_exception()

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
