So you first introduce helpers just to modify them in the next patch?

What you want to say here in this changelog is:

     genirq: Encapsulate sparse bitmap handling

     Move the open coded sparse bitmap handling into helper functions as
     a preparatory step for converting the sparse interrupt management
     to a maple tree.

     No functional change.

Hmm?

Thanks,
