- * Example of using hugepage memory in a user application using the mmap
- * system call with MAP_HUGETLB flag.  Before running this program make
- * sure the administrator has allocated enough default sized huge pages
- * to cover the 256 MB allocation.
- *
- * For ia64 architecture, Linux kernel reserves Region number 4 for hugepages.
- * That means the addresses starting with 0x800000... will need to be
- * specified.  Specifying a fixed address is not required on ppc64, i386
- * or x86_64.
