2015-05-19x86/fpu: Move the no_387 handling and FPU detection code into init.cIngo Molnar
Both no_387() and fpu__detect() run at boot time, so they belong into init.c.

2015-05-19x86/fpu: Remove unnecessary includes from core.cIngo Molnar
fpu/core.c includes a lot of files for mostly historic reasons. It only needs fpu-internal.h, which already includes all the required headers.

2015-05-19x86/fpu: Split out the boot time FPU init code into fpu/init.cIngo Molnar
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 Molnar
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.
