Let's do something like this (untested):

https://github.com/xairy/linux/commit/91354d34b30ceedbc1b6417f1ff253de90618a97

Could you reproduce this? I tried yesterday before posting the patches and my
conclusion was that kbuild robot is testing on the wrong tree.

I give it another go today, if you have more details based on your testing feel
free to share.

I haven't tried reproducing, but the error makes sense. There's no
definition of kasan_flag_async for KASAN modes other than HW_TAGS.
