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 * tag 's390-6.14-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (48 commits) s390/futex: Fix FUTEX_OP_ANDN implementation s390/diag: Add memory topology information via diag310 s390/bitops: Provide optimized arch_test_bit() s390/bitops: Switch to generic bitops s390/ebcdic: Fix length decrement in codepage_convert() s390/ebcdic: Fix length check in codepage_convert() s390/ebcdic: Use exrl instead of ex s390/amode31: Use exrl instead of ex s390/stackleak: Use exrl instead of ex in __stackleak_poison() s390/lib: Use exrl instead of ex in xor functions s390/topology: Improve topology detection s390/tlb: Add missing TLB range adjustment s390/pkey: Constify 'struct bin_attribute' s390/sclp: Constify 'struct bin_attribute' s390/pci: Constify 'struct bin_attribute' s390/ipl: Constify 'struct bin_attribute' s390/crypto/cpacf: Constify 'struct bin_attribute' s390/qdio: Move memory alloc/pointer arithmetic for slib and sl into one place s390/cio: Use array indices instead of pointer arithmetic s390/qdio: Rename feature flag aif_osa to aif_qdio ...
