x11-drivers/ati-drivers-14.4_p1 emerges fine on current kernel version (3.14.22) even though __static_cpu_has_safe seems to be GPL there too. Not sure how this can be. __static_cpu_has_safe is present in .o files shipped in ati-drivers, so I'm guessing the fact that this function declared as inline can't be the reason.
I am investigating this, the cause may be kernel_fpu_begin, could you post your kernel config anyway
Created attachment 387288 [details] 3.17.1 kernel config
Created attachment 387594 [details, diff] use-kernel_fpu_begin.patch You can try, if this works for you. I think the complicated way AMD is doing things is mostly due to the possibility of not having an FPU on the cpu. I have no idea where this happens possibly it is completely irrelevant nowadays.
Created attachment 387598 [details, diff] use-kernel_fpu_begin.patch The previous patch doesn't portage-apply, this one fixes it.
Tested with ati-drivers-14.4_p1 - built successfully and runs fine. So this patch works.
Pushed to x11 overlay
So I guess this has been applied to the main tree. Please reopen, if not.
