This "sig" definition has no references, and is shadowed by the definition below.

But, no complaint from gcc.  Trying to elicit a complaint by configuring
CC_OPTIMIZE_FOR_SIZE='n' breaks the build with:

  include/asm/desc.h: In function 'set_ldt':
  include/asm/desc.h:92: error: implicit declaration of function 'write_gdt_entry'

See reply to "[PATCH 3/4]" for a fix.
