From d8191fa4a33fdc817277da4f2b7f771ff605a41c Mon Sep 17 00:00:00 2001 From: Alex Chiang Date: Mon, 22 Feb 2010 12:11:39 -0700 Subject: ACPI: processor: driver doesn't need to evaluate _PDC Now that the early _PDC evaluation path knows how to correctly evaluate _PDC on only physically present processors, there's no need for the processor driver to evaluate it later when it loads. To cover the hotplug case, push _PDC evaluation down into the hotplug paths.
