Any lockup or stall notifies about unexpected lack of progress.
It's better to know about them for further problem investigations.

Right now only softlockup has own taint flag. Let's generalize it.

This patch renames TAINT_SOFTLOCKUP into TAINT_LOCKUP at sets it for:

Please search 'This patch' in Documentation/process/submitting-patches.rst

- softlockup
- hardlockup
- RCU stalls
- stuck in workqueues
- detected task hung

This does too many things at once and wants to be split in pieces:

  1) Change the TAINT flag and update documentation

  2) Add the tainting to the places which are not yet covered

Thanks,
