Merge tag 'kvm-x86-svm-6.16' of https://github.com/kvm-x86/linux into HEAD
KVM SVM changes for 6.16:
- Wait for target vCPU to acknowledge KVM_REQ_UPDATE_PROTECTED_GUEST_STATE to
fix a race between AP destroy and VMRUN.
- Decrypt and dump the VMSA in dump_vmcb() if debugging enabled for the VM.
- Add support for ALLOWED_SEV_FEATURES.
- Add #VMGEXIT to the set of handlers special cased for CONFIG_RETPOLINE=y.
- Treat DEBUGCTL[5:2] as reserved to pave the way for virtualizing features
that utilize those bits.
- Don't account temporary allocations in sev_send_update_data().
- Add support for KVM_CAP_X86_BUS_LOCK_EXIT on SVM, via Bus Lock Threshold.
