Christoph Hellwig b97a50adb3 mm: add remap_pfn_range_notrack
commit 74ffa5a3e68504dd289135b1cf0422c19ffb3f2e upstream.

Patch series "add remap_pfn_range_notrack instead of reinventing it in i915", v2.

i915 has some reason to want to avoid the track_pfn_remap overhead in
remap_pfn_range.  Add a function to the core VM to do just that rather
than reinventing the functionality poorly in the driver.

Note that the remap_io_sg path does get exercises when using Xorg on my
Thinkpad X1, so this should be considered lightly tested, I've not managed
to hit the remap_io_mapping path at all.

This patch (of 4):

Add a version of remap_pfn_range that does not call track_pfn_range.  This
will be used to fix horrible abuses of VM internals in the i915 driver.
