Matthieu Baerts (NGI0) 518eadd15f arch: back to -std=gnu89 in < v5.18 ... Recent fixes have been backported to < v5.18 to fix build issues with GCC 5.15. They all force -std=gnu11 in the CFLAGS, "because [the kernel] requests the gnu11 standard via '-std=' in the main Makefile". This is true for >= 5.18 versions, but not before. This switch to -std=gnu11 has been done in commit e8c07082a8 ("Kbuild: move to -std=gnu11"). For a question of uniformity, force -std=gnu89, similar to what is done in the main Makefile. Note: the fixes tags below refers to upstream commits, but this fix is only for kernels not having commit e8c07082a8 ("Kbuild: move to -std=gnu11"). Fixes: 7cbb015e2d ("parisc: fix building with gcc-15") Fixes: 3b8b80e993 ("s390: Add '-std=gnu11' to decompressor and purgatory CFLAGS") Fixes: b3bee1e7c3 ("x86/boot: Compile boot code with -std=gnu11 too") Fixes: ee2ab467bd ("x86/boot: Use '-std=gnu11' to fix build with GCC 15") Fixes: 8ba14d9f49 ("efi: libstub: Use '-std=gnu11' to fix build with GCC 15") Signed-off-by: Matthieu Baerts (NGI0) <matttbe@kernel.org> Cc: Nathan Chancellor <nathan@kernel.org> Cc: Ard Biesheuvel <ardb@kernel.org> Cc: Alexey Dobriyan <adobriyan@gmail.com> Cc: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		History 2025-12-07 06:09:15 +09:00
