Following those instructions fixes this build error for me.
Can ktr/lkp do that?
Otherwise just ignore this ERROR.

Set CONFIG_EXPERT=y
and CONFIG_LD_HEAD_STUB_CATCH=y.

However, after doing that, I get these messages:

INFO: Uncompressed kernel (size 0x30ef664) overlaps the address of the wrapper(0x400000)
INFO: Fixing the link_address of wrapper to (0x3100000)

Hi Randy,

Thanks for the explanation, We'll enable these configs.
