This patchset adds a new mode to KASAN [1], which is called KHWASAN
(Kernel HardWare assisted Address SANitizer).

We're at v6 and there are no reviewed-by's or acked-by's to be seen.
Is that a fair commentary on what has been happening, or have people
been remiss in sending and gathering such things?

I still have concerns about the consequences of merging this as anything
other than a debug option [1]. Unfortunately, merging it as a debug option
defeats the whole point, so I think we need to spend more effort on developing
tools that can help us to find and fix the subtle bugs which will arise from
enabling tagged pointers in the kernel.

I totally don't mind calling it a debug option. Do I need to somehow
specify it somewhere?

Why does it defeat the point? The point is to ease KASAN-like testing
on devices with limited memory.
