From 2e9d5e4efa0beeca03ad550bda28027826e83e42 Mon Sep 17 00:00:00 2001 From: Alex Chiang Date: Mon, 22 Feb 2010 12:11:19 -0700 Subject: [PATCH] ACPI: processor: export acpi_get_cpuid() Rename static get_cpu_id() to acpi_get_cpuid() and export it. This change also gives us an opportunity to remove the #ifndef CONFIG_SMP from processor_driver.c and into a header file where it properly belongs.
