Ideally this should have been applied before:
ssb: return correct translation bit for 64-bit DMA

This is because mentioned patch added TMSHIGH register read on every
ssb_dma_translation call which affected performance.

If we can live with affected performance between that 2 commits, please
just apply this ASAP.

It affected performance (however I don't expect anything like making it
90% slower) is not acceptable, please revert mentioned patch, apply this
one and then re-apply reverted patches.

I will be testing this patch ASAP. Unfortunately, my test box with a b43legacy device crashes on boot with wireless-testing with a fresh pull this afternoon. It does boot with commit d36a160 with only 70 commits between. It shouldn't take too long to sort out.
