This patchset adds a new hardware tag-based mode to KASAN [1]. The new mode
is similar to the existing software tag-based KASAN, but relies on arm64
Memory Tagging Extension (MTE) [2] to perform memory and pointer tagging
(instead of shadow memory and compiler instrumentation).

I have that all merged up on top of linux-next.  Numerous minor
conflicts, mainly in arch/arm/Kconfig.  Also the changes in
https://lkml.kernel.org/r/20201103175841.3495947-7-elver@google.com had
to be fed into "kasan: split out shadow.c from common.c".

I staged it after linux-next to provide visibility into potentially
conflicting changes in the arm tree as things move forward.
