The SPARC port fits the description, all the LRA related patches went in starting from December 1st (although the important issues had already been identified and a fair amount of work already been done earlier by Davem). SPARC is a very regular architecture with few, simple addressing modes so the conversion was relatively straightforward. The only irregular feature is the pairing of (even, odd) integer registers in 32-bit mode and it was the source of the annoying issues. I'm going to add a few words on the Wiki about that. -- Eric Botcazou
