  "message": "KVM: arm64: Type-check hypercall arguments at the caller\n\nkvm_call_hyp_nvhe() reduces its target to an SMCCC function number, so\nthe compiler never sees a callable: arguments that are wrong in number,\ntype or order are silently marshalled into registers. The kvm_call_hyp()\nwrappers only catch this on the VHE branch, and the pKVM-only hypercalls\nhave no such branch.\n\nDeclare each hypercall\u0027s signature once in kvm_hcall.h and generate a\ntyped stub from it, in the mold of the syscall wrappers. Make\nkvm_call_hyp_nvhe() resolve to the stub so every caller is checked\nagainst the declared signature; a stale or mistyped call now fails to\ncompile. The stubs inline to the same SMCCC call the untyped macro used\nto make: the compiled callers are unchanged, apart from hypercall\nreturns now being tested at their declared width.\n\nThe stage-2 protection arguments are declared u64 rather than\nenum kvm_pgtable_prot, as kvm_pgtable.h includes linux/kvm_host.h and\nthe enum cannot be completed here.\n\nAssisted-by: Antigravity:gemini-3.1-pro\nReviewed-by: Marc Zyngier \u003cmaz@kernel.org\u003e\nSigned-off-by: Fuad Tabba \u003cfuad.tabba@linux.dev\u003e\n",
