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
