Dan Williams 04ce9ab385 async_xor: permit callers to pass in a 'dma/page scribble' region 
async_xor() needs space to perform dma and page address conversions.  In
most cases the code can simply reuse the struct page * array because the
size of the native pointer matches the size of a dma/page address.  In
order to support archs where sizeof(dma_addr_t) is larger than
sizeof(struct page *), or to preserve the input parameters, we utilize a
memory region passed in by the caller.

Since the code is now prepared to handle the case where it cannot
perform address conversions on the stack, we no longer need the
!HIGHMEM64G dependency in drivers/dma/Kconfig.

[ Impact: don't clobber input buffers for address conversions ]
