lib/scatterlist: Introduce and export __sg_alloc_table_from_pages
Drivers like i915 benefit from being able to control the maxium
size of the sg coalesced segment while building the scatter-
gather list.
Introduce and export the __sg_alloc_table_from_pages function
which will allow it that control.
v2: Reorder parameters. (Chris Wilson)
v3: Fix incomplete reordering in v2.
v4: max_segment needs to be page aligned.
v5: Rebase.
v6: Rebase.
v7: Fix spelling in commit and mention max segment size in
__sg_alloc_table_from_pages kerneldoc. (Andrew Morton)
