Merge tag 's390-6.17-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 updates from Alexander Gordeev:

- Standardize on the __ASSEMBLER__ macro that is provided by GCC and
Clang compilers and replace __ASSEMBLY__ with __ASSEMBLER__ in both
uapi and non-uapi headers

- Explicitly include <linux/export.h> in architecture and driver files
which contain an EXPORT_SYMBOL() and remove the include from the
files which do not contain the EXPORT_SYMBOL()

- Use the full title of "z/Architecture Principles of Operation" manual
and the name of a section where facility bits are listed

- Use -D__DISABLE_EXPORTS for files in arch/s390/boot to avoid
unnecessary slowing down of the build and confusing external kABI
tools that process symtypes data

- Print additional unrecoverable machine check information to make the
root cause analysis easier

- Move cmpxchg_user_key() handling to uaccess library code, since the
generated code is large anyway and there is no benefit if it is
inlined

- Fix a problem when cmpxchg_user_key() is executing a code with a
non-default key: if a system is IPL-ed with "LOAD NORMAL", and the
previous system used storage keys where the fetch-protection bit was
set for some pages, and the cmpxchg_user_key() is located within such
page, a protection exception happens

- Either the external call or emergency signal order is used to send an
IPI to a remote CPU. Use the external order only, since it is at
least as good and sometimes even better, than the emergency signal

- In case of an early crash the early program check handler prints more
or less random value of the last breaking event address, since it is
not initialized properly. Copy the last breaking event address from
the lowcore to pt_regs to address this

- During STP synchronization check udelay() can not be used, since the
first CPU modifies tod_clock_base and get_tod_clock_monotonic() might
return a non-monotonic time. Instead, busy-loop on other CPUs, while
the the first CPU actually handles the synchronization operation

- When debugging the early kernel boot using QEMU with the -S flag and
GDB attached, skip the decompressor and start directly in kernel

- Rename PAI Crypto event 4210 according to z16 and z17 "z/Architecture
Principles of Operation" manual

- Remove the in-kernel time steering support in favour of the new s390
PTP driver, which allows the kernel clock steered more precisely

- Remove a possible false-positive warning in pte_free_defer(), which
could be triggered in a valid case KVM guest process is initializing

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

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()
