* [icp] fpu and asm cleanup for linuxGvozden Neskovic2017-03-071-0/+19
Properly annotate functions and data section so that objtool does not complain when CONFIG_STACK_VALIDATION and CONFIG_FRAME_POINTER are enabled. Pass KERNELCPPFLAGS to assembler. Use kfpu_begin()/kfpu_end() to protect SIMD regions in Linux kernel.
