[Stephen Rothwell]

Hi all,

After merging the tip tree, today's linux-next build (x86_64 allnoconfig)
produced this warning:

arch/x86/kernel/cpu/common.c: In function 'syscall_init':
arch/x86/kernel/cpu/common.c:1534:6: warning: unused variable 'cpu' 
[-Wunused-variable]
  int cpu = smp_processor_id();
      ^~~

Introduced by commit

  86635715ee42 ("x86/pti/64: Remove the SYSCALL64 entry trampoline")

Cheers,
Stephen Rothwell
