Subject[RFC v2 0/2] PPC: Add generic FPU api similar to x86
Date
This is an attempt to have generic FPU enable/disable
calls similar to x86.
So that we can simplify gpu/drm/amd/display/dc/os_types.h

Also adds FPU correctness logic seen in x86.

v2:
- Added asm/fpu/api.h powerpc variant with kernel_fpu_begin/end()
and kernel_fpu_enabled() declarations
- Updated kernel_fpu_enabled as EXPORT_SYMBOL_GPL
- Got rid of macro switch for PPC in dc/os_types.h as header file
with same name as x86 is added by previous patch in the series

Anson Jacob (2):
ppc/fpu: Add generic FPU api similar to x86
drm/amd/display: Use PPC FPU functions
