O-Subject: [RHEL5.5 PATCH]: Fix missing 32-bit syscalls on 64-bit Xen
Bugzilla: 559410

All,
     This is the followup to Wade Mealing's earlier
"[RHEL5.6 PATCH]  fix missing 32 bit syscalls on 64 bit. (BZ 559410 )"
patch.  It just wires up the syscalls for 32-bit readahead, fadvise, and
sync_file_range running on 64-bit Xen kernels.  Tested by me to work
as per the BZ.  This should solve BZ 559410.  Please review and ACK.
