* Special handling for cmpxchg_double. cmpxchg_double is passed two
* percpu variables. The first has to be aligned to a double word
* boundary and the second has to follow directly thereafter.
* We enforce this on all architectures even if they don't support
* a double cmpxchg instruction, since it's a cheap requirement, and it
* avoids breaking the requirement for architectures with the instruction.
