Yes, AT91SAM9X5 support is underway to mainline kernel.
It was posted to the mailing-list a while ago but did not reached
acceptance due to the move to device tree on ARM platforms.
We have made progress on this side recently and will add this SoC
during this effort.

So, please keep this symbol for the moment as we may need it during
our submitting of 9x5 work.
