as already discussed on IRC, this is removing a lot of symbols, which makes not much sense to me.

It appears that this commit broke the behavior of "make kernel_oldconfig":

https://github.com/openwrt/openwrt/commit/a8fb12a7d62c94fd1bbda332752e0f8c794f3702

Just reverting that commit results in something that "looks reasonable" after make kernel_oldconfig.

I'm marking that patch with "changes requested", though it's not really Rui's fault in the first place.

Let's see where this evolves to.

Best

Adrian
