-  MPSS Changes Start.
-  The JVM binary needs to be built and run on pre-Solaris 9
-  systems, but the constants needed by MPSS are only in Solaris 9
-  header files.  They are textually replicated here to allow
-  building on earlier systems.  Once building on Solaris 8 is
-  no longer a requirement, these #defines can be replaced by ordinary
-  system .h inclusion.
-
-  In earlier versions of the  JDK and Solaris, we used ISM for large pages.
-  But ISM requires shared memory to achieve this and thus has many caveats.
-  MPSS is a fully transparent and is a cleaner way to get large pages.
-  Although we still require keeping ISM for backward compatiblitiy as well as
-  giving the opportunity to use large pages on older systems it is
-  recommended that MPSS be used for Solaris 9 and above.
