    async_tx: remove HIGHMEM64G restriction · 9a8de639
    Dan Williams authored
    This restriction prevented ASYNC_TX_DMA from being enabled on platform
    configurations where DMA address conversion could not be performed in
    place on the stack.  Since commit 04ce9ab3 ("async_xor: permit callers
    to pass in a 'dma/page scribble' region") the async_tx api now either
    uses a caller provided 'scribble' buffer, or performs the conversion in
    place when sizeof(dma_addr_t) <= sizeof(struct page *).
