DMA client device driver usually needs to know at probe time whether
dma controller has been registered to deffer probe. So add a help
function of_dma_check_controller.
DMA request channel functions can also used to check it, but they
are usually called at open() time.

If tegra has only 4-core fast cpu, I would agree with the patch set. Bu

pass of_phandle_args dma_spec to dma_request_channel in of_dma_simple_xlate,
so the filter function could access of_node in of_phandle_args.
It also remove restriction of #dma-cells has to be one.

Hi Al,
I saw two commits from you in git tree:
17d1587 unexport do_munmap()
bfce281 kill mm argument of vm_munmap()
They remove the mm arguments, so it look like impossible to unmap
memory of other processes except current.
I have a kernel module that needs to unmap memory for certain pid. Do
