Please do it, since clearly I wasn't aware enough about the whole
non-TS-checking FPU state details.
Also, since this issue doesn't seem to be a recent regression, I'm not
going to take this patch directly (even though I'm planning on doing
-rc1 in a few hours), and expect that I'll get it through the normal
channels (presumably together with the __kernel_fpu_end cleanups). Ok
with everybody?
