This one seems to have received some feedback, not sure if it was
addressed or not in a subsequent patch?

> d63dd9e2afd9 [HACK] ARM: disable KASAN+XIP_KERNEL

That one has been squashed, we could always lift the XIP_KERNEL
restriction later once someone with suitable hardware confirms it works.

That one should be pushed separately.

> 053555034bdf kasan: disable CONFIG_KASAN_STACK with clang on arm32

This one I did not take based on Linus' feedback that is breaks booting
on his RealView board.

> 6c1a78a448c2 ARM: fix kasan link failures

This one was squashed relevant and will be sent out as v7.
