== Comment from Hari Krishna Bathini ==
There are quite a few commits (all available upstream) that are needed for
crash tool to work fine. I think the right thing to do here would be to use
the latest crash tool version 7.2.0 to go with the kernel update. Also, the
below commit would be needed on top of 7.2.0 crash utility:
commit c8178eca9c74f81a7f803a58d339635cc152e8d9
Author: Dave Anderson <anderson@redhat.com>
Date: Thu Nov 9 11:39:05 2017 -0500
Update for support of Linux 4.14 and later PPC64 kernels where the
hash page table geometry accomodates a larger virtual address range.
Without the patch, the virtual-to-physical translation of user space
virtual addresses by "vm -p", "vtop", and "rd -u" may generate an
invalid translation or otherwise fail.

Similar thing holds true for makedumpfile tool..

[Impact]
It won't be possible to analyze dumps produced by newer kernels (hwe on xenial, for example).
[Test Case]
Tested that this version of crash can analyze both GA (4.4) and hwe (4.15) kernels.
[Regression Potential]
New crash versions may have bugs and some commands not work with older kernels. The smoke test helps a little, but more testing may be desirable.
