Good job and thank you.

1. Install the toolchain with the following commands:
   

   Code: Select all

   sudo apt-get install gcc-powerpc-linux-gnu

   Code: Select all

   sudo apt-get install build-essential

   Code: Select all

   sudo apt-get install libncurses5-dev

2. Download the RC7:
   

   Code: Select all

   wget www.kernel.org/pub/linux/kernel/v3.x/testing/linux-3.18-rc7.tar.gz

3. Unpack the kernel archive:
   

   Code: Select all

   tar zxvf linux-3.18-rc7.tar.gz

4. Rename the directory for the Nemo patch:
   

   Code: Select all

   mv linux-3.18-rc7 linux-3.18

5. Patch the kernel source code with the Nemo patch:
   

   Code: Select all

   patch -p0 < nemo_3.18-3.patch

6. Copy the old RC6 config file to the linux-3.18 directory:
   

   Code: Select all

   cp nemo_3.18.0-rc6_KVM-PR_OVERLAYFS.config linux-3.18/.config

7. Change to the directory linux-3.18:
   

   Code: Select all

   cd linux-3.18

8. Create a RC7 config based on the old RC6 config:
   

   Code: Select all

   make CROSS_COMPILE=powerpc-linux-gnu- ARCH=powerpc oldconfig

9. Compile the Linux kernel:
   

   Code: Select all

   make CROSS_COMPILE=powerpc-linux-gnu- ARCH=powerpc vmlinux

10. With file you can check if make had built a PPC64 kernel.
    

    Code: Select all

    file vmlinux

    vmlinux: ELF 64-bit MSB executale, 64-bit PowerPC or cisco 7500, version 1 (SYSV), statically linked, BuildID[sha1]=3cec1ab0e5804eeafbfdcb249c54625336d70a6f, not stripped

11. Compile the Linux kernel modules:
    

    Code: Select all

    make CROSS_COMPILE=powerpc-linux-gnu- ARCH=powerpc modules

12. Install the Linux kernel modules:
    

    Code: Select all

    sudo make CROSS_COMPILE=powerpc-linux-gnu- ARCH=powerpc modules_install

    You can get the kernel modules from the directory /lib/modules

Cross-compiling seems to work
