That's probably detail, but as it is necessary to deeply define the HW when selecting that (I mean giving the exact amount of memory and with restrictions like having a wholeblock memory), should it also depend of EXPERT ?

Maybe we could have
- select HAVE_ARCH_KASAN_VMALLOC if PPC32 + select HAVE_ARCH_KASAN_VMALLOC if HAVE_ARCH_KASAN
