Replace the existing kasan_arch_is_ready() calls with kasan_enabled().
Drop checks where the caller is already under kasan_enabled() condition.

If I understand correctly, it means that KASAN won't work anymore 
between patch 2 and 9, because until the arch calls kasan_init_generic() 
kasan_enabled() will return false.

The transition should be smooth and your series should remain bisectable.

Or am I missing something ?

Seems right to me, it won't work for architectures that define
kasan_arch_is_ready themselves I think?

But since they have to literally #define it, could #ifdef on that
temporarily?
