From b2938f880890ebfcccad356275e0000193153623 Mon Sep 17 00:00:00 2001 From: Jeremy Fitzhardinge Date: Thu, 7 Dec 2006 02:14:03 +0100 Subject: [PATCH] i386: Implement smp_processor_id() with the PDA Use the cpu_number in the PDA to implement raw_smp_processor_id. This is a little simpler than using thread_info, though the cpu field in thread_info cannot be removed since it is used for things other than getting the current CPU in common code.
