-/* -----------------------------------------------------------------------------
-   Occationally we depend on mmap'd region being close to already mmap'd regions.
-
-   Our static in-memory linker may be restricted by the architectures relocation
-   range. E.g. aarch64 has a +-4GB range for PIC code, thus we'd preferrably
-   get memory for the linker close to existing mappings.  mmap on it's own is
-   free to return any memory location, independent of what the preferred
-   location argument indicates.
-
-   For example mmap (via qemu) might give you addresses all over the available
-   memory range if the requested location is already occupied.
-
-   mmap_next will do a linear search from the start page upwards to find a
-   suitable location that is as close as possible to the locations (proivded
-   via the first argument).
