Subject: [PATCH v1 0/4] x86/fpu: a few code cleanup

Hi all,

This series intends to clean up the x86 FPU code. They do *not* deal
with any urgent issues but considerably apparent cleanups:

- Simplify xstate_calculate_size() and print_xstate_features() as both
  have some inefficient duplications.
- Convert get_xsave_addr() to a local function because it is not
  invoked anywhere else.
- Clean up the unnecessary fpstate_reset() since the invocation makes
  no change in the fpstate container.

The last one might have an unknown reason behind it. Then, I will
revise it with the clarification instead of removing the code.

The series can be found in this repo:
	git://github.com/intel/amx-linux.git x86-fpu-cleanup

Thanks,
Chang
