RISC-V Linux kernel not booting up with KASAN enabled

[Chathura Rajapaksha]

Hi Alex,

Thank you very much, kernel booted up with the patches you mentioned.
Bootup was pretty slow compared to before though (on a dev board).
I guess that is kind of expected with KASAN enabled.
Thanks again.

Regards,
Chath
