Subject[PATCH] riscv: Pass virtual addresses to kasan_mem_to_shadow
Date
kasan_mem_to_shadow translates virtual addresses to kasan shadow
addresses whereas for_each_mem_range returns physical addresses: it is
then required to use __va on those addresses before passing them to
kasan_mem_to_shadow.

Fixes: b10d6bca8720 ("arch, drivers: replace for_each_membock() with for_each_mem_range()")
