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. --Andy
