Subject: [PATCH 0/4] x86, fpu: kernel_fpu_begin/end cleanups

Let me first try to avoid another angry email.

Sure, I understand that it is easy to say "I do not understand your code,
do not know how to test, please review".

But what else can I do if I believe it is buggy? IOW, please consider this
as the questions, not the patches. Better yet, as a bug report. Feel free
to ignore if you are busy or you are not interested enough.

But of course, I'll appreciate any comment very much.

And to remind, rightly or not I believe they need changes anyway.

Linus, according to git-log/blame you understand these paths better than
anybody else. I hope you can take a look.

Not for inclusion of course, although I hope that 1-2 and perhaps 3 make
sense anyway.

Oleg.
