In an effort to clarify and simplify the annotations of assembly
functions in the kernel new macros have been introduced replacing ENTRY
and ENDPROC. There are separate annotations SYM_FUNC_ for normal C
functions and SYM_CODE_ for other code. Currently __guest_enter and
__guest_exit are annotated as standard functions but this is not
entirely correct as the former doesn't do a normal return and the latter
is not entered in a normal fashion. From the point of view of the
hypervisor the guest entry/exit may be viewed as a single
function which happens to have an eret in the middle of it so let's
annotate it as such.
