Hi guys, I don't think maintaining that flag this in the kernel is correct... the kernel simply doesn't compile out of the box. If you grep for CONFIG_INITRAMFS_SOURCE, ARC is the only architecture that uses that kernel flag by default pointing to an external directory. I don't think this is proper to have it like this by default from the kernel point of view.
