x86/fpu: Factor out the FPU regset code into fpu/regset.c

2015-05-19T13:48:09Z

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.

x86/fpu: Factor out fpu/signal.c

2015-05-19T13:48:08Z

fpu/xstate.c has a lot of generic FPU signal frame handling routines, move them into a separate file: fpu/signal.c. Cc: Andy Lutomirski Cc: Borislav Petkov Cc: Dave Hansen Cc: Fenghua Yu Cc: H.

x86/fpu: Factor out FPU bug checks into fpu/bugs.c

2015-05-19T13:47:45Z

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.

x86/fpu: Split out the boot time FPU init code into fpu/init.c

2015-05-19T13:47:16Z

Move boot time FPU initialization code into init.c, to better isolate it into its own domain. Reviewed-by: Borislav Petkov Cc: Andy Lutomirski Cc: Dave Hansen Cc: Fenghua Yu Cc: H. Peter Anvin Cc: Linus Torvalds Cc: Oleg Nesterov Cc: Peter Zijlstra Cc: Thomas Gleixner Signed-off-by: Ingo Molnar

x86/fpu: Move i387.c and xsave.c to arch/x86/kernel/fpu/

2015-05-19T13:47:15Z

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. Reviewed-by: Borislav Petkov Cc: Andy Lutomirski Cc: Dave Hansen Cc: Fenghua Yu Cc: H.
