Subject: [PATCH 6/25 -v2] add native_apic read and write functions, as well as boot clocks ones
Date: Fri, 10 Aug 2007 16:12:18 -0300 [thread overview]
Message-ID: <11867731882768-git-send-email-gcosta@redhat.com> (raw)
In-Reply-To: <11867731831138-git-send-email-gcosta@redhat.com>
Time for the apic handling functions to get their native counterparts.
Also, put the native hook for the boot clocks functions in the apic.h header
