Hmm. So I had actually done a "allyesconfig" build on x86, which
annoys me. Because it means that the extra "let's compile everything
to make sure I didn't break anything" was just almost totally
worthless.
What seems to be happening is that the x86 <asm/uaccess.h> include
ends up getting the <linux/prefetch.h>.
I have *no* idea why x86 does that, but x86 wants prefetch.h *so* much
that it actually includes it first in <asm/uaccess.h> and then *again*
in each of the 32/64-bit specific <asm/uaccess_[32,64].h> header
files.
That seems a bit excessive. I don't think x86 should include
<linux/prefetch.h> at all, since (a) it doesn't actually use any of
it, and (b) it ended up hiding this problem from me.
Thomas, Ingo, Peter: would you be willing to just remove that stupid
header file inclusion and fix up the fallout? Instead of having these
one-by-one patches that come from Stephen testing out breakage on
other architectures that x86 simply hid due to its odd include files?
