Hello Maintainers:

  do next-* tree support powerpc POWER7 with allmodconfig ?

  I met an issue, can we bear it (or I need additional trying) ?

Compiling:
  make V=1 EXTRA_CFLAGS=-W ARCH=powerpc allmodconfig
    set cpu type POWER7 in menuconfig.
    set cross-compiler in menuconfig.
      under Fedora 16 x86_64 laptop
      /usr/bin/powerpc64-linux-gnu-gcc -v
        gcc version 4.7.1 20120606 (Red Hat 4.7.1-0.1.20120606) (GCC)

Issue:
  error:
    /android/public-kernel/linux-next/arch/powerpc/kernel/exceptions-64s.S: Assembler messages:
    /android/public-kernel/linux-next/arch/powerpc/kernel/exceptions-64s.S:1304: Error: attempt to move .org backwards

  (head_64.S includes exceptions-64.S)

  thanks.
