From c078d3266e58a3edd698b9f143f78fc585679031 Mon Sep 17 00:00:00 2001 From: Zwane Mwaikambo Date: Tue, 6 Sep 2005 15:16:16 -0700 Subject: [PATCH] [PATCH] x86_64: print processor number in show_regs Up to date I've been using the GS value to determine the processor number in dumps from show_regs, however this can be cumbersome to do if you don't have the vmlinux to verify with the address of cpu_pda, how about the following? I considered using hard_smp_processor_id for robustness but we already dereference current so we're already relying on MSR_GS_BASE being sane.
