sys-kernel/gentoo-sources-5.4.72 had CONFIG_WIREGUARD, sys-kernel/gentoo-sources-5.4.80 has it not. Reproducible: Always Steps to Reproduce: 1. Compile sys-kernel/gentoo-sources-5.4.72 with CONFIG_WIREGUARD=y 2. Copy .config to sys-kernel/gentoo-sources-5.4.80 3. Run make oldconfig 4. Run make menuconfig and search for CONFIG_WIREGUARD emerge --info: Portage 3.0.9 (python 3.7.9-final-0, default/linux/amd64/17.1/desktop, gcc-9.3.0, glibc-2.32-r2, 5.4.80-gentoo-x86_64 x86_64)
