We have added new functionality to mremap() in Linux 6.17, permitting the
move of multiple VMAs when performing a pure move (that is - providing
MREMAP_MAYMOVE | MREMAP_FIXED flags and specifying old_size == new_size).

We document this new feature.

Additionally, we document previously undocumented behaviour around
shrinking of input VMA ranges which permits the input range to span
multiple VMAs.
