Hi,
This series aims to clarify a bit the DMA API, in particular the
'size' argument which is not clear enough (as we use multiple types
for it). The clarification is trivial: add a dma_size_t typedef,
similar to the dma_addr_t one. This helps avoiding build failures
on 32-bit host [*] (and likely overflows calculation too IMO).
Some units using the DMA API are first removed from user-mode
emulation to avoid build failure (they shouldn't be there in
the first place).
Then some variables are renamed for clarity (no functional change).
Finally the dma_size_t typedef is added, and the previous patch
which failed on 32-bit host applied on top (not failing anymore).
Regards,
Phil.
