drm/i915 wants to read/write more than one page in its fastpath
and hence needs to prefault more than PAGE_SIZE bytes.
I've checked the callsites and they all already clamp size when
calling fault_in_pages_* to the same as for the subsequent
__copy_to|from_user and hence don't rely on the

This will allow us to pass more options to it in the future.

This allows to specify '-d' parameter which will decode individual bits in
each register being read.
The register bits are printed horizontally for space reasons. This
requires more than 80x25 terminal to see them all. An alternative solution
would be to print them vertically, but this will

OK, but I hope for i915 doesn't mean private to! Put 'em in
pagemap.h, for maintenance reasons and because they are generic.
