> In Fuchsia, MmapNoAccess/MmapFixedOrDie are implemented using a global
> VMAR, which means that MmapNoAccess can only be called once. This works
> for the sanitizer allocator but *not* for the Scudo allocator.
>
> Hence, this changeset introduces a new ReservedAddressRange object to
> serve as the new API for these calls. In this changeset, the object
> still calls into the old Mmap implementations.
>
> The next changeset two changesets will convert the sanitizer and scudo
> allocators to use the new APIs, respectively. (ReservedAddressRange will
> replace the SecondaryHeader in Scudo.)
>
> Finally, a last changeset will update the Fuchsia implementation.

> Patch by Julia Hansbrough
