This version is a major evolution: The physical memory allocators,
defined in the kmem.c, ppm.c, and kcm.c files have been modified
to support remote accesses. The RPCs that were previously user
to allocate physical memory in a remote cluster have been removed.
This has been done to cure a dead-lock in case of concurrent page-faults.

This version 2.2 has been tested on a (4 clusters / 2 cores per cluster)
TSAR architecture, for both the "sort" and the "fft" applications.

    231231 * descriptor, defined by the <parent_xp> argument. The <process> and <pid> arguments
    232232 * are previously allocated by the caller. This function can be called by two functions:
    233  * 1) process_init_create() : process is the INIT process, and parent is process-zero.
    234  * 2) process_make_fork() : the parent process descriptor is generally remote.
