linux-next: build warning after merge of the tip tree

[Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>]

Hi all,

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

arch/x86/kernel/traps.c: In function 'exc_double_fault':
arch/x86/kernel/traps.c:332:16: warning: unused variable 'address' [-Wunused-variable]
  332 |  unsigned long address = read_cr2();
      |                ^~~~~~~

Introduced by commit

  095b7a3e7745 ("x86/entry: Convert double fault exception to IDTENTRY_DF")

Cheers,
Stephen Rothwell
