I'm not sure what you mean here. We can remove this because it's a copy
of switch_mm above, and that's what the new header defaults to if you
don't provide an active_mm.
Patch 1 should not have changed that, it should only affect the nommu
architectures (and actually didn't touch m68k because it was not using
the asm-generic/mmu_context.h header).
Thanks,
Nick
