  x86: Detect stack protector for i386 builds on x86_64
  x86: allow "=rm" in native_save_fl()
  x86: properly annotate alternatives.c
  x86: Introduce GDT_ENTRY_INIT(), initialize bad_bios_desc statically
  x86, 32-bit: Use generic sys_pipe()
  x86: Introduce GDT_ENTRY_INIT(), fix APM
  x86: Introduce GDT_ENTRY_INIT()
  x86: Introduce set_desc_base() and set_desc_limit()
  x86: Remove unused patch_espfix_desc()
  x86: Use get_desc_base()
