this has the tendency to grow larger, no ? What if all other ARMs decide
to add their own pointers there too ? Counting the mach directories we
have:

$ ls arch/arm/ | grep mach | wc -l
64

minus a few duplicates like mach-omap1 and mach-omap2. Still, if we
count 40 different subarchs and each one of them adds their own pointer
here, this will become quite a messy piece of code, no ?

I agree we should try to have type checks, but considering the
possibility of many different pointers, does it really make sense ?
Nothing against it either, though.
