Merge tag 's390-6.14-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 updates from Alexander Gordeev:

- Select config option KASAN_VMALLOC if KASAN is enabled

- Select config option VMAP_STACK unconditionally

- Implement arch_atomic_inc() / arch_atomic_dec() functions which
result in a single instruction if compiled for z196 or newer
architectures

- Make layering between atomic.h and atomic_ops.h consistent

- Comment s390 preempt_count implementation

- Remove pre MARCH_HAS_Z196_FEATURES preempt count implementation

- GCC uses the number of lines of an inline assembly to calculate
number of instructions and decide on inlining. Therefore remove
superfluous new lines from a couple of inline assemblies.

- Provide arch_atomic_*_and_test() implementations that allow the
compiler to generate slightly better code.

- Optimize __preempt_count_dec_and_test()

- Remove __bootdata annotations from declarations in header files

- Add missing include of <linux/smp.h> in abs_lowcore.h to provide
declarations for get_cpu() and put_cpu() used in the code

- Fix suboptimal kernel image base when running make kasan.config

- Remove huge_pte_none() and huge_pte_none_mostly() as are identical to
the generic variants

- Remove unused PAGE_KERNEL_EXEC, SEGMENT_KERNEL_EXEC, and
REGION3_KERNEL_EXEC defines

- Simplify noexec page protection handling and change the page, segment
and region3 protection definitions automatically if the instruction
execution-protection facility is not available

- Save one instruction and prefer EXRL instruction over EX in string,
xor_*(), amode31 and other functions

- Create /dev/diag misc device to fetch diagnose specific information
from the kernel and provide it to userspace

- Retrieve electrical power readings using DIAGNOSE 0x324 ioctl

- Make ccw_device_get_ciw() consistent and use array indices instead of
pointer arithmetic

- s390/qdio: Move memory alloc/pointer arithmetic for slib and sl into
one place

- The sysfs core now allows instances of 'struct bin_attribute' to be
moved into read-only memory. Make use of that in s390 code

- Add missing TLB range adjustment in pud_free_tlb()

- Improve topology setup by adding early polarization detection

- Fix length checks in codepage_convert() function

- The generic bitops implementation is nearly identical to the s390
one. Switch to the generic variant and decrease a bit the kernel
image size

- Provide an optimized arch_test_bit() implementation which makes use
of flag output constraint. This generates slightly better code

- Provide memory topology information obtanied with DIAGNOSE 0x310
using ioctl.

- Various other small improvements, fixes, and cleanups

Also, some changes came in through a merge of 'pci-device-recovery'
branch:

- Add PCI error recovery status mechanism

- Simplify and document debug_next_entry() logic

- Split private data allocation and freeing out of debug file open()
and close() operations

- Add debug_dump() function that gets a textual representation of a
debug info (e.g. PCI recovery hardware error logs)

- Add formatted content of pci_debug_msg_id to the PCI report

s390/diag324: Retrieve power readings via diag 0x324

Retrieve electrical power readings for resources in a computing
environment via diag 0x324. diag 0x324 stores the power readings in the
power information block (pib).

Provide power readings from pib via diag324 ioctl interface. diag324
ioctl provides new pib to the user only if the threshold time has passed
since the last call. Otherwise, cache data is returned. When there are
no active readers, cleanup of pib buffer is performed.

major here, it's a bit bigger than it might've been due to there being

Merge tag 's390-6.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 updates from Vasily Gorbik:

- Optimize ftrace and kprobes code patching and avoid stop machine for
kprobes if sequential instruction fetching facility is available

- Add hiperdispatch feature to dynamically adjust CPU capacity in
vertical polarization to improve scheduling efficiency and overall
performance. Also add infrastructure for handling warning track
interrupts (WTI), allowing for graceful CPU preemption

- Rework crypto code pkey module and split it into separate,
independent modules for sysfs, PCKMO, CCA, and EP11, allowing modules
to load only when the relevant hardware is available

- Add hardware acceleration for HMAC modes and the full AES-XTS cipher,
utilizing message-security assist extensions (MSA) 10 and 11. It
introduces new shash implementations for HMAC-SHA224/256/384/512 and
registers the hardware-accelerated AES-XTS cipher as the preferred
option. Also add clear key token support

- Add MSA 10 and 11 processor activity instrumentation counters to perf
and update PAI Extension 1 NNPA counters

- Cleanup cpu sampling facility code and rework debug/WARN_ON_ONCE
statements

- Add support for SHA3 performance enhancements introduced with MSA 12

- Add support for the query authentication information feature of MSA
13 and introduce the KDSA CPACF instruction. Provide query and query
authentication information in sysfs, enabling tools like cpacfinfo to
present this data in a human-readable form

- Update kernel disassembler instructions

- Always enable EXPOLINE_EXTERN if supported by the compiler to ensure
kpatch compatibility

- Add missing warning handling and relocated lowcore support to the
early program check handler

- Optimize ftrace_return_address() and avoid calling unwinder

- Make modules use kernel ftrace trampolines

- Strip relocs from the final vmlinux ELF file to make it roughly 2
times smaller

- Dump register contents and call trace for early crashes to the
console

- Generate ptdump address marker array dynamically

- Fix rcu_sched stalls that might occur when adding or removing large
amounts of pages at once to or from the CMM balloon

- Fix deadlock caused by recursive lock of the AP bus scan mutex

- Unify sync and async register save areas in entry code

- Cleanup debug prints in crypto code

- Various cleanup and sanitizing patches for the decompressor

- Various small ftrace cleanups

s390/crypto: Display Query and Query Authentication Information in sysfs

Displays the query (fc=0) and query authentication information (fc=127)
as binary in sysfs per CPACF instruction. Files are located in
/sys/devices/system/cpu/cpacf/. These information can be fetched via
asm already except for PCKMO because this instruction is privileged. To
offer a unified interface all CPACF instructions will have this
information displayed in sysfs in files <instruction>_query_raw and
<instruction>_query_auth_info_raw.

A new tool introduced into s390-tools called cpacfinfo will use this
information to convert and display in human readable form.

s390/hiperdispatch: Introduce hiperdispatch

When LPAR is in vertical polarization, CPUs get different polarization
values, namely vertical high, vertical medium and vertical low. These
values represent the likelyhood of the CPU getting physical runtime.
Vertical high CPUs will always get runtime and others get varying
runtime depending on the load the CEC is under.

Vertical high and vertical medium CPUs are considered the CPUs which the
current LPAR has the entitlement to run on. The vertical lows are on the
other hand are borrowed CPUs which would only be given to the LPAR by
hipervisor when the other LPARs are not utilizing them.

Using the CPU capacities, hint linux scheduler when it should prioritise
vertical high and vertical medium CPUs over vertical low CPUs.
By tracking various system statistics hiperdispatch determines when to
adjust cpu capacities.
After each adjustment, rebuilding of scheduler domains is necessary to
notify the scheduler about capacity changes but since this operation is
costly it should be done as sparsely as possible.
