6 KASAN is supported on both hash and nohash MMUs on 32-bit.
23 - It would be good to support inline instrumentation so as to be able to catch
24 stack issues that cannot be caught with outline mode.
26 - Inline instrumentation requires a fixed offset.
28 - Book3S runs code with translations off ("real mode") during boot, including a
29 lot of generic device-tree parsing code which is used to determine MMU
32 - Some code - most notably a lot of KVM code - also runs with translations off
35 - Therefore any offset has to point to memory that is valid with
