OK to install?
I can't say I really like this new interface, I'd prefer two wrappers aarch64_legitimate_address_p , aarch64_legitimate_ldp_address_p (or similar) around your new interface, and for most code to simply call the wrapper. Or an overloaded call that filled in ADDR_QUERY_M automatically, to save that spreading through the backend.
