i915_gem_object_map implements fairly low-level vmap functionality in
a driver. Split it into two helpers, one for remapping kernel memory
which can use vmap, and one for I/O memory that uses vmap_pfn.
The only practical difference is that alloc_vm_area prefeaults the
vmalloc area PTEs, which doesn't seem to be required here for the
kernel memory case (and could be added to vmap using a flag if actually
required).
Patch looks good to me.
Series did not get a CI run from our side because of a different base so I
don't know if you would like to have a run there? If so you would need to
rebase against git://anongit.freedesktop.org/drm-tip drm-tip and you could
even send a series to intel-gfx-trybot@xxxxxxxxxxxxxxxxxxxxx, suppressing
cc, to check it out without sending a copy to the real mailing list.
It doesn't seem like I can post to any freedesktop list, as I always
get rejection messages. But I'll happily prepare a branch if one
of you an feed it into your CI.
That's fine, just ping me and I will forward it for testing, thanks!

Tvrtko
