How was it tested? Can you write some documentation for it?

I'd rather not select it, given the recent issues with the binary
size, and the fact that this has been tested only on one, quite
recent, SoC so far.

How about an imply? or a default y?

I thought the arm64 kernels were uncompressed?

That should probably be in a separate patch anyway.
