Subject: [PATCH 20/52] provide hlt_works function.
Date: Mon, 3 Mar 2008 14:12:48 -0300 [thread overview]
Message-ID: <1204564400-17636-21-git-send-email-gcosta@redhat.com> (raw)
In-Reply-To: <1204564400-17636-20-git-send-email-gcosta@redhat.com>
In x86_64, hlt always work. in i386, we'll query the cpuinfo associated
with this cpu
