Sorry Bruce, but I don't have a clue what you are talking about here.

On Xeon, as 512b accesses are available, movdir64 instruction is able to
perform 512b read and write to DLB producer port. In order for movdir64
to be able to pull its data from store buffers (store-buffer-forwarding)
(before actual write), data should be in single 512b write format.
