From: Pawan Gupta <pawan.kumar.gupta@xxxxxxxxxxxxxxx> Add the new cpu family ATOM_TREMONT_D to the cpu vunerability whitelist. ATOM_TREMONT_D is not affected by X86_BUG_ITLB_MULTIHIT. ATOM_TREMONT_D might have mitigations against other issues as well, but only the ITLB multihit mitigation is confirmed at this point.
