remap_vmalloc_range clenaups

[Christoph Hellwig]

Hi Andrew,

this series removes an open coded instance of remap_vmalloc_range and
removes the unused remap_vmalloc_range_partial export.

[PATCH 1/2] samples/vfio-mdev/mdpy: use remap_vmalloc_range

[Christoph Hellwig]

Use remap_vmalloc_range instead of open coding it using
remap_vmalloc_range_partial.

[Christoph Hellwig]

remap_vmalloc_range_partial is only used to implement remap_vmalloc_range
and by procfs.  Unexport it.
