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).
