RAD_SUPPORT

   RAD_SUPPORT enables RAD-aware code to be executed
   on systems that support Resource Affinity Domains (RADs);
   for example, AlphaServer GS160 systems and Integrity 
   cell-based servers or BL8x0c i2 servers. A RAD is a set of
   hardware components (CPUs and memory) with common access
   characteristics.

   Bits are defined in the RAD_SUPPORT parameter as follows:

   RAD_SUPPORT (default is 207 for Alpha and 10944667 
   for Integrity servers)

   Bit 0 (e): Enable    - Enables RAD support

   Bit 1 (a): Affinity  - Enables Soft RAD Affinity (SRA) scheduling
                          Also enables the interpretation of the skip
                          bits, 24-27.

   Bit 2 (r): Replicate - Enables system-space code replication

   Bit 3 (c): Copy      - Enables copy on soft fault

   Bit 4 (f): Fault     - Enables special page fault allocation
                          Also enables the interpretation of the
                          allocation bits, 16-23.

   Bit 5 (d): Debug     - Reserved to VSI

   Bit 6 (p): Pool      - Enables per-RAD non-paged pool

   Bits 7-15:           - Reserved to VSI

   Bits 16-23:          - If bit 4 is set, bits 16-23 are interpreted
                          as follows:

   Bits 16,17 (pp): Process = Pagefault on process (non global)
                              pages
   Bits 18,19 (ww): Swapper = Swapper's allocation of pages for
                              processes
   Bits 20,21 (gg): Global  = Pagefault on global pages
   Bits 22,23 (ss): System  = Pagefault on system space pages

   Encodings for pp, ww, gg, ss:
   Current  (0) - allocate PFNs from the current CPU's RAD
   Random   (1) - allocate PFNs using the "random" algorithm
   Base     (2) - allocate PFNs from the operating system's "base"
                  RAD
   Home     (3) - allocate PFNs from the current process's home RAD

   If bits 16-23 are 0, the defaults for pp, ww, gg, ss are interpreted
   as follows:

       Process = home RAD
       Swapper = current RAD (also sets home RAD for process)
       Global  = random RAD
       System  = base RAD

   Bits 24-27:   - If bit 1 is set, bits 24-27 are interpreted
                   as a skip count value (power of 2). Example: If
                   bits 24-27 contain a 3, the skip count is 8.
                   If bits 24-27 contain a 5, the skip count is 32.
                   If bits 24-27 are 0, the default of 16 is used
                   as the skip count.

   Bits 28-31:   - Reserved to VSI
