2015-05-19x86/fpu: Factor out the FPU regset code into fpu/regset.cIngo Molnar1-1/+1
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.

2015-05-19x86/fpu: Factor out fpu/signal.cIngo Molnar1-1/+1
fpu/xstate.c has a lot of generic FPU signal frame handling routines, move them into a separate file: fpu/signal.c.

2015-05-19x86/fpu: Factor out FPU bug checks into fpu/bugs.cIngo Molnar1-1/+1
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.

2015-05-19x86/fpu: Split out the boot time FPU init code into fpu/init.cIngo Molnar1-1/+1
Move boot time FPU initialization code into init.c, to better isolate it into its own domain.

2015-05-19x86/fpu: Move i387.c and xsave.c to arch/x86/kernel/fpu/Ingo Molnar1-0/+5
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.
