Kernel for A64 git

[Pirin]

Hi longsleep,

I was able to download the source code for '3.10.65-5-pine64' onto my Pin64.  From there, I modified the 'arch/arm64/configs/sun50iw1p1smp_linux_defconfig' file to add the line "CONFIG_USB_ACM=m".  Once I rebuilt the kernel and modules, I was able to insert the new cdc-acm.ko module into your 3.10.65-5 kernel on my Pine64 board and communicate with my external serial device.

It would be great to see the ACM module included in future builds.  Is there a way that I can contribute this change?  Both Linux and GitHub are relatively new to me, but I am willing to try.

Thank you.
