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

Hi Eric,

After merging the userns tree, today's linux-next build (i386 defconfig)
produced this warning:

arch/x86/mm/fault.c: In function 'do_sigbus':
arch/x86/mm/fault.c:1017:22: warning: unused variable 'tsk' [-Wunused-variable]
  struct task_struct *tsk = current;
                      ^~~

Introduced by commit

  351b6825b3a9 ("signal: Explicitly call force_sig_fault on current")

The remaining used of "tsk" are protected by CONFIG_MEMORY_FAILURE.

Cheers,
Stephen Rothwell
