Declare what? I can't parse your statement.

The most importang goal with kernel code is improvement and less bugs.
Unification is second. We should not jump through hoops and unify at
every price just because there's a duplicated function somewhere.
Remember that when doing your changes.

Not really. I can imagine why Robert suggested that but this strategy is
causing unnecessary churn. What one usually does in such cases is:

1. Add changes to the target functionality - the one in cper.c - by
explaining *why* those changes are needed.

2. Switch ghes_edac.c to that functionality and remove the redundant one
there.

Simple and clean diffstat and easy review.

Thx.
