#     powerpc/powernv/idle: Fix restore of SPRN_LDBAR for POWER9 stop state.
#     
#     commit 10d91611f426 ("powerpc/64s: Reimplement book3s idle code in C")
#     reimplemented book3S code to pltform/powernv/idle.c. But when doing so
#     missed to add the per-thread LDBAR update in the core_woken path of
#     the power9_idle_stop(). Patch fixes the same.
#
