[PATCH 0/3] b43 & bcma: DMA special (translation) bits

["Rafał Miłecki" <zajec5@gmail.com>]

Thanks to Pavel's comments I digged into translation bits and found out
the hackish way we currently use to handle 32-bit and 64-bit DMA.

I've replaced out bit shifting hacks with just a one, documented in the
comment. This workaround ideally should be just fixed, but I'm not going
to blidly change the current behaviour of ssb_dma_translation without
testing that with b43legacy and b44. As I don't have such a hardware,
we will need to find some testers.

In any case, the way we changed the code should be correct. When ssb
function will be fixed, b43 will only require deletion of 2 code lines.

I've tested this code for regressions on my following cards:
1) 14e4:432b (64-bit DMA)
2) 14e4:4315 (64-bit DMA)
3) 14e4:4312 (32-bit DMA)
Transmission is still possible on all of them, no errors were noticed.


Pavel: sorry for CC-ing you with my previous serie. Fortunately this
lead to the much nicer solution, thanks for your help.
I let myself yo CC you once more, as this patch serie tries to fix
issues you pointed to me.
