Function mmtk::policy::marksweepspace::malloc_ms::metadata::map_meta_space

pub(super) fn map_meta_space(
    metadata: &SideMetadataContext,
    addr: Address,
    size: usize
)

We map the active chunk metadata (if not previously mapped), as well as the VO bit metadata and active page metadata here. Note that if [addr, addr + size) crosses multiple chunks, we will map for each chunk.
