Pull s390 updates from Alexander Gordeev: - Use CIO device online variable instead of the internal FSM state to determine device availability during purge operations - Remove extra check of task_stack_page() because try_get_task_stack() already takes care of that when reading /proc/<pid>/wchan - Allow user-space to use the new SCLP action qualifier 4 for to provide NVMe SMART log data to the platform. - Send AP CHANGE uevents on successful bind and successful association to notify user-space about SE operations on AP queue devices - Add an s390dbf kernel parameter to configure debug log levels and area sizes during early boot - On arm64 the empty zero page is going to be mapped read-only. Do the same for s390 with an explicit set_memory_ro() call - Improve s390-specific bcr_serialize() and cpu_relax() implementations - Remove all unused variables to avoid allmodconfig W=1 build fails with latest clang-23 - Cleanup default Kconfig values for s390 selftests - Add a s390-tod trace clock to allow comparing trace timestamps between different systems or virtual machines on s390 - Remove the s390 implementation of strlcat() in favor of the generic variant - Make consistent the calling order between page_table_check_pte_clear() and secure page conversion across all code paths - Rearrange some fields within AP and zcrypt structs to reduce memory consumption and unused holes - Shorten GR_NUM and VX_NUM macros and move them to a separate header - Replace __get_free_page() with kmalloc() in few sources - Introduce an infrastructure for more efficient this_cpu operations. Eliminate conditional branches when PREEMPT_NONE is removed - Enable Rust support - Use z10 as minimum architecture level, similar to the boot code, to enforce a defined architecture level set - Improve and convert various mem*() helper functions to C. For that add .noinstr.text section to avoid orphaned warnings from the linker - Fix the function pointer type in __ret_from_fork() to correct the indirect call to match kernel thread return type of int - Revert support for DCACHE_WORD_ACCESS to avoid an endless exception loop on read from donated Ultravisor pages at unaligned addresses * tag 's390-7.2-1' of gitolite.kernel.org:pub/scm/linux/kernel/git/s390/linux: (52 commits) s390: Revert support for DCACHE_WORD_ACCESS s390/process: Fix kernel thread function pointer type s390/tishift: Convert __ashlti3(), __ashrti3(), __lshrti3() to C s390/memmove: Optimize backward copy case s390/string: Convert memset(16|32|64)() to C s390/string: Convert memcpy() to C s390/string: Convert memset() to C s390/string: Convert memmove() to C s390/string: Add -ffreestanding compile option to string.o s390: Add .noinstr.text to boot and purgatory linker scripts s390/purgatory: Enforce z10 minimum architecture level s390: Enable Rust support s390/cmpxchg: Fix KASAN stack-out-of-bounds in atomic helpers rust: helpers: Add memchr wrapper for string operations rust/bindgen_parameters: Mark s390 types as opaque to prevent repr conflicts s390/jump_label: Implement ARCH_STATIC_BRANCH_JUMP_ASM and ARCH_STATIC_BRANCH_ASM macros s390/bug: Provide ARCH_WARN_ASM for Rust WARN/BUG support s390/ap: Fix locking issue in SE bind and associate sysfs functions s390/percpu: Provide arch_this_cpu_write() implementation s390/percpu: Provide arch_this_cpu_read() implementation ...
