Mostly idle thoughts at this stage, I haven't looked seriously. I have an old patch set to batch forks (and mprotect etc...) TLB invalidations (which is what I really want to batch on powerpc, more than the actual PTE changes) that involves subtle changes to the batching mechanisms etc... but it has issues and would need to be reworked before merging. It's something that's been in the back of my mind or the bottom of my TODO list for some time, but I never quite found the bandwidth to go back to it.
