Ok, patch 7-9 of this series do not depend on this patch nor number 6.  I will
resend those 3 while I figure out what to do about these 2:

staging/rdma/hfi1: Add function stubs for TID caching
staging/rdma/hfi1: Implement Expected Receive TID caching

Frankly this was an attempt to reduce the size of "Implement Expected Receive
TID caching".  I obviously did something wrong.

I really don't know that I can split these up any more without causing issues
with bisecting the code.
