I've not seen Thomas attack anyone in this thread - I've seen him getting
rightfully grumpy at sub-par code quality of the Intel uncore driver...

Stop these personal attacks and stop insulting people why try to clean up the mess
you made of a driver!
Thomas found real bugs in the driver and presented a much cleaner model for
representing uncore PMUs, which results in nice simplifications:
2 files changed, 139 insertions(+), 220 deletions(-)
if these changes survive review and testing then they are very much 'worth it',
and that fact should be apparent to you as well.
Thanks,
Ingo
