OK, I'll add in code to handle this.

Kexec should work for all combinations of kernel options. A
bootloader (1st stage) may want to be UP, and custom crash
dump kernels (2nd stage) are generally UP. UP->UP may have
limited use. I think all these listed are important to test
though, and going the other way also, so BE-SMP->LE-SMP for
example.
