The driver should not need more than 4096 bytes for a single allocation.
If the ppc64 page size is smaller, your patch is ok, otherwise something
may have to be fixed, likely in the driver. I cannot access to kernel
source immediately but I will check what kind of page size ppc64 is using

Thanks for your report.
