Abbott submitted a v5 about a year ago here:

and the series was not picked up since then, so I rebased it against
v5.2-rc4 and re-tested it on a Brahma-B53 (ARMv8 running AArch32 mode)
and Brahma-B15, both LPAE and test-kasan is consistent with the ARM64
counter part.

We were in a fairly good shape last time with a few different people
having tested it, so I am hoping we can get that included for 5.4 if
everything goes well.

Thanks for picking this up. I was trying out KASan in the past,
got sidetracked and honestly lost interest a bit because it was
boring. But I do realize that it is really neat, so I will try to help
out with some review and test on a bunch of hardware I have.

At one point I even had this running on the ARMv4 SA1100
(no joke!) and if I recall correctly, I got stuck because of things
that might very well have been related to using a very fragile
Arm testchip that later broke down completely in the l2cache
when we added the spectre/meltdown fixes.

A blast from the past!

I start reviewing and testing.

Great, thanks a lot for taking a look. FYI, I will be on holiday from
July 19th till August 12th, if you think you have more feedback between
now and then, I can try to pick it up and submit a v7 with that feedback
addressed, or it will happen when I return, or you can pick it up if you
refer, all options are possible!

@Arnd, should we squash your patches in as well?
