[Linux-ia64] Greater than 2TB Filesystem support?

["Eastham, M. Thomas (Anitel Technologies)" <EasthaMT@bp.com>]

Is there anyone out there that can give me an indication of when the 2TB FS
limitation will be addressed?  We are ready to implement XFS based IDE Raid
IA64 servers with 4+TB today.  Any information you can provide me about
timelines would be very helpful.

Regards,
Thomas Eastham

The first set is wrong.  There is also an error in ia64/config.in for
one of these variables.  Patch against 2.4.19.
