Subject: [PATCH v9 2/7] x86/cpu: Add Tremont to the cpu vulnerability whitelist
This patch adds new cpu family ATOM_TREMONT_D to the cpu vunerability
whitelist. ATOM_TREMONT_D is not affected by X86_BUG_ITLB_MULTIHIT. There
may be more bugs not affecting ATOM_TREMONT_D which are not known at
this point and could be added later.
