[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.
