Hello, first time poster so apologies if I posted to the wrong list. Anyone knows why the SPARC makefiles (arch/sparc/Makefile and arch/sparc/vdso/Makefile) set `-fcall-used-g5` and `-fcall-used-g7` in their CFLAGS? Would it be safe if the kernel is compiled without those flags? The context is that there's an effort to make the sparc64 kernel build under LLVM/clang, and if possible we'd like to build the kernel without those flags, at least when building with clang, since it simplifies a lot of things on the LLVM side.
