  "message": "KVM: arm64: nVHE: Check hypercall handlers against the declared ABI\n\nEach hypercall handler unmarshals its arguments from the host context\nwith hand-written DECLARE_REG() casts that nothing ties to what the\ncaller passed: a handler can disagree with its caller in argument type,\ncount or register index without a diagnostic.\n\nGenerate the unmarshalling instead. DEFINE_KVM_HOST_HCALL() expands to\nthe handle_\u003cname\u003e() glue, modelled on the syscall wrappers, and checks\nthe handler\u0027s parameter list against the signature declared in\nkvm_hcall.h, so both ends of every hypercall are now compiled against\nthe same declaration. Handler bodies keep their logic and lose the\nDECLARE_REG() and return-register boilerplate. The two\nget_host_hyp_vcpus() macros existed only to wrap DECLARE_REG(), so one\nis dropped and the other becomes a function. The compiled handlers are\ninstruction-for-instruction identical, apart from flush_hyp_vcpu() and\nsync_hyp_vcpu() now being inlined into their only caller.\n\nThe return-register store is picked by the declared return type, so a\nvoid handler needs no macro of its own. The type is pasted into the\nstore\u0027s name, which has to be a single word, so\n__pkvm_create_private_mapping is declared ulong.\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",
