mm/rmap: rename vma_interval_tree_*() to mapping_rmap_tree_*()
The family of vma_interval_tree_() functions manipulate the
address_space (which, of course, is generally referred to as 'mapping')
reverse mapping, but are named the 'VMA' interval tree.
VMAs may be mapped by an anon_vma, an address_space, or both. Therefore
calling the mapping interval tree a 'VMA' interval tree is rather
confusing.
This is also inconsistent with the anon_vma_interval_tree_*() functions
which explicitly reference the rmap object to which they pertain.
Rename the vma_interval_tree_*() functions to mapping_rmap_tree_*() to
correct this.
We will rename the anon rmap functions similarly in a subsequent patch.
No functional change intended.
