Each process will have its own callbacks. Callbacks will indicate whether it's allocation and deallocation that's happened, and will also provide start VA address and length of allocated block. Since memory hotplug isn't supported on FreeBSD and in legacy mem mode, it will not be possible to register them in either. Callbacks are called whenever something happens to the memory map of current process, therefore at those times memory hotplug subsystem is write-locked, which leads to deadlocks on attempt to use these functions. Document the limitation.
