From 46ba51ea8f8639da32c55744b35479fdfb4e7232 Mon Sep 17 00:00:00 2001 From: Hanjun Guo Date: Fri, 18 Jul 2014 18:02:54 +0800 Subject: ACPI / processor: Introduce ARCH_MIGHT_HAVE_ACPI_PDC The use of _PDC is deprecated in ACPI 3.0 in favor of _OSC, as ARM platform is supported only in ACPI 5.0 or higher version, _PDC will not be used in ARM platform, so make Make _PDC only for platforms with Intel CPUs. Introduce ARCH_MIGHT_HAVE_ACPI_PDC and move _PDC related code in ACPI processor driver into a single file processor_pdc.c, make x86 and ia64 select it when ACPI is enabled. This patch also use pr_* to replace printk to fix the checkpatch warning and factor acpi_processor_alloc_pdc() a little bit to avoid duplicate pr_err() code.
