Title:
Ubuntu 17.10 crashes on vmalloc.c
Status in The Ubuntu-power-systems project:

Bug description:
== SRU Justification ==
IBM is seeing a crash on Power9 when running on Artful.
This issue happens only when disabling RPT ("disable_radix"), which is not
the default in Artful.
These fixes are already in Bionic master-next, so they are only being
requested
in Artful.
== Fixes ==
63ee9b2ff9d3 ("powerpc/mm/book3s64: Make KERN_IO_START a variable")
b5048de04b32 ("powerpc/mm/slb: Move comment next to the code it's")
21a0e8c14bf6 ("powerpc/mm/hash64: Make vmalloc 56T on hash")
== Regression Potential ==
These commits are specific to powerpc and fix a crash.
== Test Case ==
A test kernel was built with these patches and tested by the original bug
reporter.
The bug reporter states the test kernel resolved the bug.
== Comment: #0 - Breno Leitao - 2017-12-19 09:48:10 ==
When running Ubuntu 17.10 on POWER9, I got the following error:
