Jiri Slaby 76dc6d6001 x86/asm/entry: Annotate THUNKs
Place SYM_*_START_NOALIGN and SYM_*_END around the THUNK macro body.
Preserve @function by FUNC (64bit) and CODE (32bit). Given it was not
marked as aligned, use NOALIGN.

The result:
 Value  Size Type    Bind   Vis      Ndx Name
  0000    28 FUNC    GLOBAL DEFAULT    1 trace_hardirqs_on_thunk
  001c    28 FUNC    GLOBAL DEFAULT    1 trace_hardirqs_off_thunk
  0038    24 FUNC    GLOBAL DEFAULT    1 lockdep_sys_exit_thunk
  0050    24 FUNC    GLOBAL DEFAULT    1 ___preempt_schedule
  0068    24 FUNC    GLOBAL DEFAULT    1 ___preempt_schedule_notra

The annotation of .L_restore does not generate anything (at the moment).
Here, it just serves documentation purposes (as opening and closing
brackets of functions).
