Old style exception processing?

[André Keller Abadie]

Hi guys

I'm working with the smc91111 NIC driver and I found this message:

/*
 *  This driver currently only supports architectures with the old style
 *  exception processing.  The following checks try to keep this
 *  from being compiled on systems which can't support this driver.
 *
 *  NOTE: As of 28 September 2005, this has only been tested on the SPARC,
 *        so that is all it is enabled for.
 */

What does 'old style exception processing' mean? What are the
differences to the new one?

Thanks in advance,

André--
