| |
Nathan Lynch <ntl@pobox.com> reported: 2.6.23-rc1 breaks the build for 64-bit powerpc for me (using maple_defconfig):
LD vmlinux.o powerpc64-unknown-linux-gnu-ld: dynreloc miscount for kernel/built-in.o, section .opd powerpc64-unknown-linux-gnu-ld: can not edit opd Bad value make: *** [vmlinux.o] Error 1
However, I see a possibly related binutils patch: http://article.gmane.org/gmane.comp.gnu.binutils/33650
It was tracked down to be caused by the weak prototype declaration in mm.h: __attribute__((weak)) const char *arch_vma_name(struct vm_area_struct *vma);
But there is no need to make the declaration weak - only the definition needs to be marked weak. So drop the weak declaration. And in the process drop the duplicate definition in page.h for powerpc.
Signed-off-by: Sam Ravnborg <sam@ravnborg.org> --- Note - the arch_vma_name fix for x86_64 needs to be applied first to avoid breaking x86_64
