This seems reasonable in principle, but IMO it would be less scary if
you rebased onto this:

https://git.kernel.org/cgit/linux/kernel/git/luto/linux.git/log/?h=x86/fpu

Because the amount of testing needed and the amount of code that gets
rearranged would be reduced.  Want to fold those patches into you
series?  I can also just send them in directly, although this is an
awkward time to do so.
