Public bug reported:

[Impact]
When using Ubuntu to debug 4.0 kernels, crash fails with something as follows:
WARNING: kernels compiled by different gcc versions:
  vmlinux-4.0.0-rc7: (unknown)
  dump.201504151428 kernel: 4.9.1

WARNING: kernel version inconsistency between vmlinux and dumpfile

crash: incompatible arguments: 
   vmlinux-4.0.0-rc7 is not SMP -- dump.201504151428 is SMP

[Test Case]
Try to use crash with a 4.0+ kernel crash.
This should work.

[Fix]
