mm: isolate mmap internal logic to mm/vma.c
In previous commits we effected improvements to the mmap() logic in
mmap_region() and its newly introduced internal implementation function
__mmap_region().
However as these changes are intended to be backported, we kept the delta
as small as is possible and made as few changes as possible to the newly
introduced mm/vma.* files.
Take the opportunity to move this logic to mm/vma.c which not only
isolates it, but also makes it available for later userland testing which
can help us catch such logic errors far earlier.
