That said, seeing the full history of this same thing on the x86-32 side
actually makes me _much_ happier about the patch. Because now I can tell
when we did it, and what problems it seems to have caused (answer:
"apparently none that are possibly relevant on x86-64").

IOW, just seeing the fact that we used to behave the same, and then
changed it on the 32-bit side (with no apparent big issues) and did it
without updating the 64-bit side, makes me just much happier about your
patch. Just because I know know the background to why this was x86-64
only.

So now I'm considering just putting it in before the 2.6.26 release after
all ;)
