0c306bcfba x86/fpu: Factor out the FPU regset code into fpu/regset.c 
So much of fpu/core.c is the regset code, but it just obscures the generic
FPU state machine logic. Factor out the regset code into fpu/regset.c, where
it can be read in isolation.

This affects one API: fpu__activate_stopped() has to be made available
from the core to fpu/regset.c.

No change in functionality.

b992c660d3 x86/fpu: Factor out fpu/signal.c 
fpu/xstate.c has a lot of generic FPU signal frame handling routines,
move them into a separate file: fpu/signal.c.

0bf23f3d6c x86/fpu: Factor out FPU bug checks into fpu/bugs.c 
Create separate fpu/bugs.c code so that if we read generic FPU code
we don't have to wade through all the bugcheck related code first.

0c86753790 x86/fpu: Split out the boot time FPU init code into fpu/init.c 
Move boot time FPU initialization code into init.c, to better
isolate it into its own domain.

ce4c4c2624 x86/fpu: Move i387.c and xsave.c to arch/x86/kernel/fpu/ 
Create a new subdirectory for the FPU support code in arch/x86/kernel/fpu/.

Rename 'i387.c' to 'core.c' - as this really collects the core FPU support
code, nothing i387 specific.

We'll better organize this directory in later patches.
