Oh. I just realized. That was your _baseline_ in the comparisons, wasn't it?

Can you please make the baseline be the current mainline git version
of <asm/uaccess.h>, not the first "unsigned long long __val_gu8"
version of the 64-bit get_user()?

Because we should compare against the straightforward code, not the
one that could have messed things up already..
