Hi all,
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.

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.

Use the remap_pfn_range_notrack helper instead of directly messing
with PTEs.

It's not _notrack it's "rely on the tracking established by the struct
io_mapping". Exporting a _notrack version to drivers sounds like not
something we want to ever do. So I think you want a helper which takes the
io_mapping, and not something that encourages drivers to go full stupid.

Needs an older machine and old userspace. intel-gfx CI should still check
whether it's all ok.

As far as I can tell there is no struct io_mapping anywhere near
remap_io_sg.

Yeah that looks like real bad taste, but it is how this stuff is (or at
least was, been years I've followed this closely) meant to work. Comment
in the code still claims it's the way:
/* We rely on prevalidation of the io-mapping to skip track_pfn(). */
If that's a lie and there's no iomapping for that range, then ugh.
