Trick question. MIPS CPUs *are* indeed bi-endian, but one has to choose 
endianness upon system initialization. Originally PowerPC were also like 
that, endianness at initialization, but one can mix little- and 
big-endian VMs[!] on POWER8 and forward.

Right, not at the same time. Userland has to match the kernel endianness.

Cheers.
