You should use ARCH_SUNXI_SMP instead to avoid confusion with the actual
MCPM code. Ditto for function names as Dave mentioned.

For the ARM to Thumb switch you could add something like this at the
beginning of your entry code:

#ifdef CONFIG_THUMB2_KERNEL
.arm
mov ip, #1
bx ip
.thumb
#endif
[your code follows here]

And make sure that code is word aligned.
