Hi I am trying to compile windrvr6 (a driver for USB and Parallel JTAG cable for use with Xilinx FPGA devices) on a x64 Fedora Core 8 with a 2.6.26.3-14 kernel.
I get the following error message

linux_wrappers.c:306: error: unknown field ‘nopage’ specified in initializer
linux_wrappers.c:306: warning: initialization from incompatible pointer type

which seems to tbe caused by these lines in linux_wrappers.c

struct vm_operations_struct windriver_vm_ops = {
    nopage:     windriver_vma_nopage,
};

Below is the output of the compile command.
