the corresponding mitigations for the arm64 architecture. Original
advisory details:

 Jann Horn discovered that microprocessors utilizing speculative execution
 and indirect branch prediction may allow unauthorized memory reads via
 sidechannel attacks. This flaw is known as Meltdown. A local attacker could
 use this to expose sensitive information, including kernel memory.
