--- Comment #8 from Christophe Leroy (christophe.leroy@c-s.fr) ---
Thanks for the test.
Looking once more at module_alloc() in arch/powerpc/mm/kasan/kasan_init_32.c, I
think we are missing an initialisation.
In module_alloc(), in the call to __vmalloc_node_range(), could you try and
replace GFP_KERNEL by GFP_KERNEL | __GFP_ZERO
