Subject: [PATCH 0/8] sched: Rework task state printing

With wider usage of TASK_IDLE came a few user visible annoyances. Markus
reported that TASK_IDLE is reported as TASK_UNINTERRUPTIBLE and some tools like
htop mark those highly visible, which is not warranted for TASK_IDLE.

This patch set reworks the task-state printing and introduces explicit handling
for TASK_IDLE and TASK_PARKED.
