Call kasan_init_generic() which enables the static flag to mark generic KASAN initialized, otherwise it's an inline stub.
Replace `kasan_arch_is_ready` with `kasan_enabled`. Delete the flag `kasan_early_stage` in favor of the global static key enabled via kasan_enabled(). printk banner is printed earlier right where `kasan_early_stage` was flipped, just to keep the same flow.
