Subject: linux-next: build warning after merge of the rcu tree

Hi Paul,

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

kernel/cpu.c: In function 'boot_cpu_state_init':
kernel/cpu.c:1778:6: warning: unused variable 'cpu' [-Wunused-variable]
  int cpu;
      ^

Introduced by commit

  faeb334286b7 ("rcu: Migrate callbacks earlier in the CPU-offline timeline")

Cheers,
Stephen Rothwell
