I think this would be valuable to get into -rc1 since we're getting very close to a GCC 15 release. Can someone get this into -tip urgent, please? If everyone is busy I can take it via the hardening tree, as we appear to be the ones tripping over it the most currently. :) -Kees > [1]: https://lore.kernel.org/4OAhbllK7x4QJGpZjkYjtBYNLd_2whHx9oFiuZcGwtVR4hIzvduultkgfAIRZI3vQpZylu7Gl929HaYFRGeMEalWCpeMzCIIhLxxRhq4U-Y=@protonmail.com/ > [2]: https://lore.kernel.org/Z4467umXR2PZ0M1H@tucnak/ > > --- > Nathan Chancellor (2): > x86/boot: Use '-std=gnu11' to fix build with GCC 15 > efi: libstub: Use '-std=gnu11' to fix build with GCC 15 > > arch/x86/boot/compressed/Makefile | 1 + > drivers/firmware/efi/libstub/Makefile | 2 +- > 2 files changed, 2 insertions(+), 1 deletion(-) > --- > base-commit: ffd294d346d185b70e28b1a28abe367bbfe53c04 > change-id: 20250121-x86-use-std-consistently-gcc-15-f95146e0050f > > Best regards, > -- > Nathan Chancellor <nathan@xxxxxxxxxx> > -- Kees Cook
