How to enable/bring Ambient capabilities in Kernel 3.12

Hi All,

Ambient capabilities are supporting in from Linux 4.3).
We are looking for the feasibility options on back porting Ambient capabilities changes in older Kernel 3.12.

Do we have any existing patch for this backporting?

Or do we have any limitations in Kernel 3.12 to support ambient capabilities?

Can someone please clarify the above query?

Thanks
