Deduplicate checks for whether the current context is safe for spin_trylock(). Does this function really belong in mm/internal.h or is it generic? Not sure. If someone ends up duplicating this logic elsewhere in the kernel, that would be a shame. But if it goes in some generic header, someone treats it as documentation about where it's guaranteed safe to spin_trylock(), and then it emerges that there are other subtle preconditions that didn't affect the mm usecase, that would be worse. So, just be conservative and keep it local.
