[icp] fpu and asm cleanup for linux
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. Reviewed-by: Tom Caputi <tcaputi@datto.com> Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Gvozden Neskovic <neskovic@gmail.com> Closes #5872 Closes #5041
