From 1d9cb470a755409ce97c3376174b1e234bd20371 Mon Sep 17 00:00:00 2001 From: Alex Chiang Date: Sun, 20 Dec 2009 12:19:14 -0700 Subject: ACPI: processor: introduce arch_has_acpi_pdc arch dependent helper function that tells us if we should attempt to evaluate _PDC on this machine or not. The x86 implementation assumes that the CPUs in the machine must be homogeneous, and that you cannot mix CPUs of different vendors. Cc: Tony Luck Cc: Thomas Gleixner Cc: Ingo Molnar Cc: "H.
