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.

The patch is fine. In fact, I didn't notice much difference in CPU usage in the
before/after tests; however, my b43legacy device only handles 802.11b, thus
there are not a lot of packets per second.
The failure to boot with the latest pull is more problematic. My bisection try
led to the nonsensical result of a branch commit. I will pull mainline 3.0 to
see if it has the same problem.
