Taint kernel after WARN_ON(condition)
The kernel is sent to tainted within the warn_on_slowpath() function, and whenever a warning occurs the new taint flag 'W' is set. This is useful to know if a warning occurred before a BUG by preserving the warning as a flag in the taint state. This does not work on architectures where WARN_ON has its own definition. These archs are: 1. s390 2. superh 3. avr32 4. parisc The maintainers of these architectures have been added in the Cc: list in this email to alert them to the situation. The documentation in oops-tracing.txt has been updated to include the new flag.
