This series performs a series of cleanups and improvements around how the
vma->vm_pgoff field is used.

Folios belonging to file-backed mappings are simply indexed by the page
offset within the file they map (excepting pfnmap and driver mappings which
sometimes do things different).

However, anonymous folios belonging to pure anonymous mappings are indexed
by their "virtual" page offset, which is equal to addr >> PAGE_SHIFT at the
time at which the VMA was first faulted in.

The page offset of a VMA is stored in vma->vm_pgoff and indicates the page
offset of the start of the VMA range, whether it be file-backed or
anonymous.

The work here both cleans up how we reference this field, as well as laying
the foundations for a future series which addresses the inconsistency of
CoW'd folios in MAP_PRIVATE-file backed mappings, which are indexed as if
they were file-backed but behave as if they were anonymous.

This future series will make it such that all anonymous folios are indexed
by virtual page offset whether belonging to VMAs who satisfy
vma_is_anonymous() or MAP_PRIVATE-mapped file-backed mappings.

This series:

* Exposes vma_start_pgoff() and updates the kernel to use it consistently.
* Adds and uses the useful vma_end_pgoff() helper.
* Parameterises the file-backed mapping helpers vma_interval_tree_*()
  by address_space rather than rb_root_cached.
* Renames: the misleadingly-named vma_interval_tree_*() helpers to
  mapping_rmap_tree_*() to be consistent with the renamed
  anon_rmap_tree_*().
* Parameterises anon_rmap_tree_*() by anon_vma.
* Moves mm/interval_tree.c to the rmap section.
* Adds vmg_*() helpers for page offset.
* Clarifies the confusing vmg_adjust_set_range() function.
* Introduces linear_page_delta() to provide relative pgoff within a VMA.
* Replaces open-coded versions of linear_page_delta() and
  linear_page_index() with invocations of these functions.
* Introduces and uses vma_assert_can_modify() to account for whether a VMA
  can be modified (detached or write locked).
* Adds and uses vma_[add,sub]_pgoff() to adjust VMA page offset.
* Moves __install_special_mapping() to vma.c.
* Makes vma_set_range() static and internal to vma.c.
* Introduces and makes use of vma_set_pgoff().
* Fixes incorrect vma.h header inclusion.
* Defaults VMA userland tests to 64-bit vma flags size.
* Updates VMA userland tests to give better output on failure.
* Various smaller cleanups.
* Updated the vma_set_pgoff() assert to account for MAP_PRIVATE /dev/zero
  correctly.

v2:
* Rebased on mm-unstable.
* Updated tags (thanks to everyone and b4 trailers -F -u! ;)
* Updated 1/30 to include the vma_start_pgoff() helper in VMA userland tests,
  which was previously causing a bisection hazard on the VMA userland tests.
* Updated 2/30 to reference the pfnmap vma->vm_pgoff PFN abomination as per
  David.
* Updated 4/30 to include vma_end_pgoff() helper in VMA userland tests at the
  appropriate point.
* Updated 8/30 from mapping_interval_tree_*() to mapping_rmap_tree_*() and add
  commit to rename anon_vma_interval-tree_*() to anon_rmap_tree_*()  as per
  Pedro.
* Fixed issue in 8/30 where the internal helpers were still called
  __vma_interval_tree_*() rather than __mapping_rmap_tree_*().
* Updated 9/30 to separate out the rename and change of parameter type for
  clarity as per Gregory.
* Updated 17/30 to put perf_mmap_aux() variables in reverse Christmas tree order
  as per Pedro.
* Updated 19/30 to remove incorrectly placed vma_start_pgoff() invocation as per
  Thomas/Gregory.
* Updated 20/30, 21/30 to put the vma_assert_can_modify() VMA userland test stub
  in the right place as per Pedro.
* Confined the vma_set_pgoff() assert to CONFIG_MMU, as the ever helpful
  nommu of course violates all assumptions in this regard.
* Fixed issue in improved ASSERT_[TRUE, FALSE, EQ, NE] test runners with
  re-evaluation of input expressions.
* Updated the vma_start_pgoff() comment further to discuss the MAP_PRIVATE
  /dev/zero edge case.
* Update the vma_set_pgoff() assert to handle the mmap_region() newly
  established file mapping case.
* Updated the linear_page_index() comment to explicitly defer to
  vma_start_pgoff() to avoid duplicate information and future bitrot.
* Updated vma_shrink() to no longer accept the useless start parameter, as
  it is invoked from relocate_vma_down() only, which has already expanded
  the VMA to cover the range [new_start, old_end) thus always shrinks the
  tail.
* Moved sanity checks from vma_set_pgoff() to new helper
  assert_sane_pgoff() and documented it clearly.
* Fixed issue with nascent file-backed VMAs hitting vma_set_pgoff() assert
  by checking for vma_is_anonymous().
* Moved vma_set_anonymous() earlier so vma_set_pgoff() works with nascent
  anonymous VMAs.
* Updated the VMA userland tests so CONFIG_MMU, CONFIG_PER_VMA_LOCK work
  with IS_ENABLED().
