-         By default, zsmalloc uses a copy-based object mapping method to
-         access allocations that span two pages. However, if a particular
-         architecture (ex, ARM) performs VM mapping faster than copying,
-         then you should select this. This causes zsmalloc to use page table
-         mapping rather than copying for object mapping.
