When building defconfig the following warning shows up:

arch/sh/kernel/traps.c: In function 'nmi_trap_handler':
arch/sh/kernel/traps.c:183:15: warning: unused variable 'cpu' [-Wunused-variable]
  unsigned int cpu = smp_processor_id();
               ^~~

Remove an unused variable 'cpu'.

Fixes: fe3f1d5d7cd3 ("sh: Get rid of nmi_count()")

Good catch. Now I have one warning less when building the kernel for my SH-7785LCR ;-).
