== 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.
The trace and details of the crash are posted to the bug.
These fixes are already in Bionic master-next, so they are only being requested
== 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.
