[PATCH] [8/50] x86_64: remove x86_cpu_to_log_apicid

From: Andi Kleen
Date: Fri Sep 21 2007 - 18:34:42 EST



From: Mike Travis <travis@xxxxxxx>

Remove the x86_cpu_to_log_apicid array. It is set in
arch/x86_64/kernel/genapic_flat.c:flat_init_apic_ldr() and
arch/x86_64/kernel/smpboot.c:do_boot_cpu() but it is never
referenced.
