[OpenAFS-devel] Kdump on ia64_linux26

[Mike Becher]

This patch make kdump work on ia64_linux26. It is nice to find out more 
about kernel structures ;-).

Summary:
  * src/venus/Makefile 
    changes to install kdump binary as kdump-<kernelversion>
    Old version overwrites kdump script with binary.
  * src/venus/kdump.c
    - let CPP overwrite flock64 with flock for IA64
    - int is 4 bytes on ia64 so I use long instead for address calculation
      and to read kernel structures

comment:
  It works only on ia64_linux26 but not on {i386,amd64}_linux26.

best regards,
  mike
