[PATCH 022/208] x86/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.
