Linus, please let me > know if you want me to spin it. I can do it sunday night. 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).
