fix 'dynreloc miscount' link error on Powerpc

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.

Note: the arch_vma_name fix for x86_64 needs to be applied first to avoid
breaking x86_64
