As these counters are for debugging only and unused, we can just
remove them.

This statement is false.

Care to check again with the mainline kernel? All the mainline
code was doing was incrementing these.

The kick counters were there to work around HW quirks/bugs not for any kind of debugging.  Code in this area was added reactively to customer production failures not for expirmentation.

It seems likely the assembly with some effort could be made to keep its function.

It sounds like we have never had those pieces in the mainline
kernel though?

Regards,

Tony
