Date: Fri, 1 Nov 2019 00:33:44 +0100 [thread overview]
Message-ID: <1572564827-26288-3-git-send-email-pbonzini@redhat.com> (raw)
In-Reply-To: <1572564827-26288-1-git-send-email-pbonzini@redhat.com>
From: Pawan Gupta <pawan.kumar.gupta@linux.intel.com>
Subject: [PATCH v8 2/5] 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.
