This patch series implements KASAN on 64-bit POWER with radix MMU,
such as POWER9 or POWER10.  Daniel Axtens posted previous versions of
these patches, but is no longer working on KASAN, and I have been
asked to get them ready for inclusion.

Because of various technical difficulties, mostly around the need to
allow for code that runs in real mode, we only support "outline" mode
(as opposed to "inline" mode), where the compiler adds a call to
a checking procedure before every store to memory.
