The runtime patching of the kernel is useful for simple and straight-forward cases such as SMP ops which are performed in assembly. But in this case I'm afraid this could add even more overhead in the end, especially when highmem is active. But if the overhead of simply enabling highmem is not significant enough to be measurable in the first place then this is moot.
Agreed; let's benchmark and decide whether it's worth thinking about :)
