That is was oversight. I have pushed updates to the branch here:
https://github.com/ffainelli/linux/pull/new/kasan-v7
which defines CONFIG_KASAN_SHADOW_OFFSET from the PAGE_OFFSET value
directly, and recalculate KASAN_SHADOW_START/END accordingly using the
same formula as ARM64.
can you try them out? If that still does not work, can you detail the
imx6qdp memory layout a little more? Any chance of running a kernel with
DEBUG_LL/EARLYPRINTK turned on so we can see where the problem could be?
