From 2f4dfe206a2fc07099dfad77a8ea2f4b4ae2140f Mon Sep 17 00:00:00 2001 From: Fernando Luis Vazquez Cao Date: Wed, 9 May 2007 02:33:25 -0700 Subject: Remove hardcoding of hard_smp_processor_id on UP systems With the advent of kdump, the assumption that the boot CPU when booting an UP kernel is always the CPU with a particular hardware ID (often 0) (usually referred to as BSP on some architectures) is not valid anymore. The reason being that the dump capture kernel boots on the crashed CPU (the CPU that invoked crash_kexec), which may be or may not be that particular CPU. Move definition of hard_smp_processor_id for the UP case to architecture-specific code ("asm/smp.h") where it belongs, so that each architecture can provide its own implementation.
