This also breaks dmabounce when used with a highmem-enabled system -
dmabounce refuses the dma_map_page() API but allows the dma_map_single()
API.

I really not sure how this change will break dma bounce code. 

Does it mean that it is allowed to call dma_map_single() on kmapped HIGH_MEM 
page?

dma_map_single on a kmapped page already doesn't work, the argument needs to
be inside of the linear mapping in order for virt_to_page to work.
