Last user of PAGE_KERNEL_IO is the i915 driver. While removing it from
there as we seek to bring the driver to other architectures, Daniel
suggested that we could finish the cleanup and remove it altogether,
through the tip tree. So here I'm sending both commits needed for that.

thanks, Peter.

The intention was to merge this through the tip tree. Although now I'm
not sure. Options:

1) take the first patch through the drm-intel tree and apply the
second patch later
2) take everything through the drm tree
3) take everything through the tip tree

What's your preference here?
