Hi,
I have a kernel module which works fine with linux X86 combo.
But when I try to compile it with mips cross toll chain it compiles well but insmod gives me error on "_gp_disp" unknown symbol.
How do I get rid of that ??? Do I need to do anything special with my compiler flags.

_gp_disp is a magic symbol references to which are only generated by the
assembler when generating PIC code, so you simply compiled using the
wrong options. Add ``-fno-pic -mno-abicalls'' to the options and this
problem will go away.
BTW,I find this in google, may it will be help to you !

Which provides aproximately zero proof for the correctness of your code,
sorry ...

Read the FAQ, it's described there.
