    [POWERPC] Fix Oops with TQM5200 on TQM5200
    
    The "bestcomm-core" driver defines its of_match table as follows
    
    static struct of_device_id mpc52xx_bcom_of_match[] = {
    	{ .type = "dma-controller", .compatible = "fsl,mpc5200-bestcomm", },
    	{ .type = "dma-controller", .compatible = "mpc5200-bestcomm", },
    	{},
    };
    
    so while registering the driver, the driver's probe function won't be
    called, because the device tree node doesn't have a device_type
    property.  Thus the driver's bcom_engine structure won't be allocated.
    Referencing this structure later causes observed Oops.
    
    Checking bcom_eng pointer for NULL before referencing data pointed
    by it prevents oopsing, but fec driver still doesn't work (because
    of the lost bestcomm match and resulted task allocation failure).
    Actually the compatible property exists and should match and so
    the fec driver should work.
    
    This removes .type = "dma-controller" from the bestcomm driver's
    mpc52xx_bcom_of_match table to solve the problem.

    [POWERPC] mpc5200: Fix null dereference if bestcomm fails to initialize
    
    If the bestcomm initialization fails, calls to the task allocate
    function should fail gracefully instead of oopsing with a NULL deref.

    [POWERPC] mpc5200-fec: Fix possible NULL dereference in mdio driver
    
    If the reg property is missing from the phy node (unlikely, but possible),
    then the kernel will oops with a NULL pointer dereference.  This fixes
    it by checking the pointer first.

    [POWERPC] Fix crash in init_ipic_sysfs on efika
    
    The global primary_ipic in arch/powerpc/sysdev/ipic.c can remain NULL
    if ipic_init() fails, which will happen on machines that don't have an
    ipic interrupt controller.  init_ipic_sysfs() will crash in that case.

    [POWERPC] Don't use 64k pages for ioremap on pSeries
    
    On pSeries, the hypervisor doesn't let us map in the eHEA ethernet
    adapter using 64k pages, and thus the ehea driver will fail if 64k
    pages are configured.  This works around the problem by always
    using 4k pages for ioremap on pSeries (but not on other platforms).
    A better fix would be to check whether the partition could ever
    have an eHEA adapter, and only force 4k pages if it could, but this
    will do for 2.6.25.
    
    This is based on an earlier patch by Tony Breeds.
