Hi all, the memory allocation for the TTM pool is a big mess with two allocation methods that both have issues, a layering violation and odd guessing of pools in the callers.
This patch switches to the dma_alloc_noncoherent API instead fixing all of the above issues. Warning: i don't have any of the relevant hardware, so this is a compile tested request for comments only!
