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. # # Fixes: 10d91611f426 ("powerpc/64s: Reimplement book3s idle code in C") # Cc: stable@vger.kernel.org # v5.2+ # Signed-off-by: Athira Rajeev # Signed-off-by: Madhavan
