kdb v4.3 for 2.5.72 ia64

kdb v4.3 for 2.5.72 ia64

[Xavier Bru]

Hello all,

I updated the previous port of kdb on 2.5.72 ia64 to kdb v4.3 on:
	         http://www.bullfreeware.com/linux/kdb 

It has same limitations, just a fix for calling bh_enable() only when
interrupts are enabled (Problem is seen on 2.5 when kdb() is called
from kdb_ipi(), due to 	WARN_ON() in this code, but also exists in 2.4).

Hoping this can help. Please don't expect too much fixes from me until 
september.

Xavier
