So do the usual dance of hiding them before including vmlinux.h, and then redefining them and make use of CO-RE to have the correct offsets.

About a fourth of it is a new selftest, and a couple more changes are large in number of files touched (fixing a -Wflex-array-member-not-at-end compiler warning) or lines changed (reformatting of a table in the API documentation, thanks rST). But who am I kidding---it's a lot of commits and there are a lot of bugs being fixed here, some of them on the nastier side like the RISC-V ones. ARM: - Correctly handle deactivation of interrupts that were activated from LRs. Since EOIcount only denotes deactivation of interrupts that are not present in an LR, start EOIcount deactivation walk *after* the last irq that made it into an LR - Avoid calling into the stubs to probe for ICH_VTR_EL2.TDS when pKVM is already enabled -- not only thhis isn't possible (pKVM will reject the call), but it is also useless: this can only happen for a CPU that has already booted once, and the capability will not change - Fix a couple of low-severity bugs in our S2 fault handling path, affecting the recently introduced LS64 handling and the even more esoteric handling of hwpoison in a nested context - Address yet another syzkaller finding in the vgic initialisation, where we would end-up destroying an uninitialised vgic with nasty consequences - Address an annoying case of pKVM failing to boot when some of the memblock regions that the host is faulting in are not page-aligned - Inject some sanity in the NV stage-2 walker by checking the limits against the advertised PA size, and correctly report the resulting faults PPC: - Fix a PPC e500 build error due to a long-standing wart that was exposed by the recent conversion to kmalloc_obj(); rip out all the ugliness that led to the wart RISC-V: - Prevent speculative out-of-bounds access using array_index_nospec() in APLIC interrupt handling, ONE_REG regiser access, AIA CSR access, float register access, and PMU counter access - Fix potential use-after-free issues in kvm_riscv_gstage_get_leaf(), kvm_riscv_aia_aplic_has_attr(), and kvm_riscv_aia_imsic_has_attr() - Fix potential null pointer dereference in kvm_riscv_vcpu_aia_rmw_topei() - Fix off-by-one array access in SBI PMU - Skip THP support check during dirty logging - Fix error code returned for Smstateen and Ssaia ONE_REG interface - Check host Ssaia extension when creating AIA irqchip x86: - Fix cases where CPUID mitigation features were incorrectly marked as available whenever the kernel used scattered feature words for them - Validate _all_ GVAs, rather than just the first GVA, when processing a range of GVAs for Hyper-V's TLB flush hypercalls - Fix a brown paper bug in add_atomic_switch_msr() - Use hlist_for_each_entry_srcu() when traversing mask_notifier_list, to fix a lockdep warning; KVM doesn't hold RCU, just irq_srcu - Ensure AVIC VMCB fields are initialized if the VM has an in-kernel local APIC (and AVIC is enabled at the module level) - Update CR8 write interception when AVIC is (de)activated, to fix a bug where the guest can run in perpetuity with the CR8 intercept enabled - Add a quirk to skip the consistency check on FREEZE_IN_SMM, i.e. to allow L1 hypervisors to set FREEZE_IN_SMM. This reverts (by default) an unintentional tightening of userspace ABI in 6.17, and provides some amount of backwards compatibility with hypervisors who want to freeze PMCs on VM-Entry - Validate the VMCS/VMCB on return to a nested guest from SMM, because either userspace or the guest could stash invalid values in memory and trigger the processor's consistency checks Generic: - Remove a subtle pseudo-overlay of kvm_stats_desc, which, aside from being unnecessary and confusing, triggered compiler warnings due to -Wflex-array-member-not-at-end - Document that vcpu->mutex is take outside of kvm->slots_lock and kvm->slots_arch_lock, which is intentional and desirable despite being rather unintuitive Selftests: -
