I have tried the patch on kernel version 2.4.28 and it seems that the fix is not working for this kernel version. I used gcc version 2.95.4 and it is working. Another questions: I am using 32 bit application and 64 bit device driver that I wrote. ioctl fails with "unknown ioctl" message. 1. What is the best way to translate 32 bit ioctl codes to 64 bit? 2. How 64 bit kernel space buffers will be used by a 32 bit application (using mmap)? 3.What is the maximum usable ram out of 2GB I will have if I am using a 32 bit application and 64 bit kernel and the kernel is allocating the buffers using __get_free_pages (I need the buffers for DMA - and I need them to be physically continuous)?
