Thanks.

Grub has its own printf code, as it can't use glibc, and the grub_printf function doesn't support FP format codes. So this should not be a problem for grub. FYI In the git tree, grub changed from using +nofp to -mgeneral-regs-only on June 2, because the kernel uses -mgeneral-regs-only, and because +nofp was broken in gcc-5-branch. But we still needed the patch backported for people who could not or didn't want to upgrade grub. Jim
