When the context tracking feature was backported to 3.14 LSK,
setting of the LR was moved out of the main body of el0_sync
and into the applicable sub handlers (i.e. el0_da, el0_sp_pc,
etc). The el0_dbg handler was overlooked. The implication
is that do_debug_exception() will attempt to return directly
to userspace without going through the ret_from_exception
path. This ultimately results in another sync exception due
to a protection fault on the target PC.
This was introduced by:
commit 333625b7586d2753a77f32e1f898ab7cc6cf7655
