I applied these patches to 2.4 also:

ChangeSet@1.1009.1.16, 2003-03-07 12:02:17-07:00, davidm@tiger.hpl.hp.com
  ia64: In kernel unwinder, replace dump_info_pt() with get_scratch_regs()
        and reformat to make it fit in 100 columns.

ChangeSet@1.1009.1.15, 2003-03-07 12:02:07-07:00, davidm@tiger.hpl.hp.com
  ia64; Improve debug output from kernel unwinder.  Based on patch by
        Keith Owens.  (Ported to 2.4 by Bjorn Helgaas).

ChangeSet@1.1009.1.14, 2003-03-07 12:01:27-07:00, kaos@sgi.com
  [PATCH] ia64: fix scratch-regs handling in kernel unwinder
  
  This patch has been running inside SGI for 2 months.  It
  handles kernel stacks with multiple struct pt_regs, as found
  while debugging the kernel.
