--- Comment #17 from John Paul Adrian Glaubitz <glaubitz at physik dot fu-berlin.de> --- (In reply to Rich Felker from comment #16) > The kernel build regression is just a gratuitous unresolved symbol; the code > path where is happens should not be reachable or the kernel would crash. So > I think the patch as-is is fine for fixing that issue. I'm testing the patch right now. Already rebuild gcc with the patch and I'm now building the kernel with that gcc.
