Andy Lutomirski b0dc553cfc x86/fpu: Make the EFI FPU calling convention explicit ... EFI uses kernel_fpu_begin() to conform to the UEFI calling convention. This specifically requires initializing FCW (FPU Control Word), whereas no sane 64-bit kernel code should use legacy 387 operations that reference FCW. This should allow to safely change the default semantics of kernel_fpu_begin() to stop initializing FCW on 64-bit kernels.
