So, thanks for starting on this. But it needs to go into
arch/arm/Kconfig. And I meant, it should be default y if CPU_V7, and
depend on !ARM64 (because we don't have asm versions of these functions,
we could borrow them from the kernel, and someone should I suspect).
The key here is that on some older ARM cores we will exceed the SPL size
limit with these functions enabled. Make sense? Thanks!
