Can you tell me, What is the difference between BSP kernel and mainline kernel? What i must do with mainline kernel to get BSP kernel?

The BSP (= Board Support Package) kernel contains patches provided by Allwinner to make the stock Linux kernel run on their SoC. Some of theses patches may interfere with the RT patches.

You can download the mainline 3.10.65 kernel here and run diffs against the BSP kernel for the files indicated above.
Then you need to identify the sections affected by the RT patch in the BSP kernel or run the patch against the mainline sources and compare the files mentioned above before and after applying the RT patch with their BSP kernel counterpart.

Part in BSP kernel which swears RT patch:
