Is there some reason this patch is not getting pushed into mainline ?

    The request below give rise to the problem.
    I have some boards equiped with MPC8247 and FPGA without storage
    media which used as a PCI interface. So when the linux bootup
    before initialize the PCI, the code of FPGA will download. I
    append the FPGA code file in the Kernel section '.init.text'. when
    linux bootup firstly it check the board type(different board type
    would download different code), and download fpga code. More board
    types lead to more FPGA code. I append them all in the section of
    '.init.text'. when the total size of the code reach out 2M. The
    error occured. I read the '__log_buf' the kernel access some bad
    area. As the powerpce603 will map 16M address use two bat, how and
    why the problem occured, and how to solved it .

    

Since the error occurs at 2M, I am going to guess it is similar to
problem I had. The default link/load address for booting is 0x200000.

Here is a link:

This fix is for the arch/ppc tree. I don't know if the arch/powerpc tree
works the same way.

In the future, you should say what kernel version you are using and what
the error was.
