+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.19/older/patches-4.19.25-rt16.tar.xz
+
+In cpu_chill() the state is set to TASK_UNINTERRUPTIBLE and a timer is
+programmed. On return the state is always TASK_RUNNING which means we
+lose the state if it was something other than RUNNING. Also
+set_current_state() sets ->task_state_change to within cpu_chill() which
+is not expected.
+
+Save the task state on entry and restore it on return. Simply set the
+state in order to avoid updating ->task_state_change.
