Subject: [MODERATED] [PATCH v6 2/5] NX 2
Date: Fri, 11 Oct 2019 12:40:13 +0200 [thread overview]
Message-ID: <1570790416-25882-3-git-send-email-pbonzini@redhat.com> (raw)
In-Reply-To: <1570790416-25882-1-git-send-email-pbonzini@redhat.com>
This patch adds new cpu family ATOM_TREMONT_X to the cpu vunerability
whitelist. ATOM_TREMONT_X is not affected by X86_BUG_ITLB_MULTIHIT. There
may be more bugs not affecting ATOM_TREMONT_X which are not known at
this point and could be added later.
