The reality is that changing something fundamental like the kernel stack at this point for an architecture that will not change in the future is silly.
x86_32 will no longer have updates, but will x86_64? And we will constantly be adding more work around hacks to handle the difference of the pt_regs in the future. I see Peter's patch easing that future pain.
The reality is that Peter's patch is much bigger than mine, because it needed a lot of other changes *because* it did that change.
It was much bigger because it removed a lot of the work around hacks.
But you are the "benevolent dictator", and I don't see me changing your mind.
I'll go and implement it the way you like.
