After a while I got it to compile for i386. arm didn't go so well, partly because arm allmodconfig is presently horked (something to do with Kconfig not setting PHYS_OFFSET) and partly because arm defconfig doesn't permit CMA to be set. Got bored, gave up.
That's not going to get fixed, unfortunately. It requires us to find some way to force various options to certain states on all*config builds, because not surprisingly a value of 'y', 'm' or 'n' doesn't work for integer or hex config options.
So the only way all*config can be used on ARM is with a seed config file to force various options to particular states to ensure that we end up with a sane configuration that avoids crap like that.
Alternatively, we need a way to tell kconfig that various options are to be set in certain ways in the Kconfig files for all*config to avoid it wanting values for hex or int options.
