Hi Expert, please advise if I did anything wrong when compiling modules

Install Ubuntu 12.04 in virtualbox, clone the source of linux-3.4-sunxi from github, did some code editing and compile the modules with arm-linux-gnueabi-* . But when playing around on Fedora 22, I cannot load the module and receive "Invalid module format" error. Here is the output of modinfo, file and readelf -h, any clues?

output of modinfo of bundled sunxi-ir-rx.ko

code:

I precisely wished to appreciate you again. I am not sure what I would’ve worked on in the absence of those techniques provided by you concerning that industry. This has been the scary case in my opinion, but taking note of the skilled avenue you processed it took me to jump over contentment. I am happy for your advice and in addition hope you recognize what an amazing job you are always doing training people through the use of a web site. I’m certain you haven’t got to know any of us.        rút tiền 69vn
