The device endianness doesn't change during runtime.
What are you talking about? Of course it does.I mean, it doesn't often in practice, because the Linux kernel is compiled for one endianness and doesn't keep toggling state, but the hooks that you're replacing test for the *current* endianness state of the cpu. So this is a behaviour change.
Have you considered that the bootloader and the kernel may use different endianness? r~
