+What:   ACPI hooks (X86_SPEEDSTEP_CENTRINO_ACPI) in speedstep-centrino driver
+When:   December 2006
+Why:    Speedstep-centrino driver with ACPI hooks and acpi-cpufreq driver are
+        functionally very much similar. They talk to ACPI in same way. Only
+        difference between them is the way they do frequency transitions.
+        One uses MSRs and the other one uses IO ports. Functionaliy of
+        speedstep_centrino with ACPI hooks is now merged into acpi-cpufreq.
+        That means one common driver will support all Intel Enhanced Speedstep
+        capable CPUs. That means less confusion over name of
+        speedstep-centrino driver (with that driver supposed to be used on
+        non-centrino platforms). That means less duplication of code and
+        less maintenance effort and no possibility of these two drivers
+        going out of sync.
+        Current users of speedstep_centrino with ACPI hooks are requested to
+        switch over to acpi-cpufreq driver. speedstep-centrino will continue
+        to work using older non-ACPI static table based scheme even after this
+        date.
