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() * tag 's390-6.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (54 commits) s390/mm: Fix VM_FAULT_HWPOISON handling in do_exception() s390/kvm: Move bitfields for dat tables s390/entry: Pass the asce as parameter to sie64a() s390/sthyi: Use cached data when diag is busy s390/sthyi: Move diag operations s390/hypfs_diag: Diag204 busy loop s390/diag: Add busy-indication-facility requirements s390/diag: Diag204 add busy return errno s390/diag: Return errno's from diag204 s390/sclp: Diag204 busy indication facility detection s390/atomic_ops: Make use of flag output constraint s390/atomic_ops: Improve __atomic_set() for small values s390/atomic_ops: Use symbolic names s390/smp: Switch to GENERIC_CPU_DEVICES s390/hwcaps: Add documentation for HWCAP flags s390/pgtable: Make crdte() and cspg() return a value s390/topology: Remove CPU KOBJ_CHANGE uevents s390/sclp: Add timeout to Store Data requests s390/sclp: Prevent release of buffer in I/O s390/sclp: Suppress unnecessary Store Data warning ...
