So, what exactly is broken in upstream? make defconfig works as it always did.Auto-detection of SUBARCH, which can be done with a simple call to uname -m (the 90% case). The second patch I submitted prevented spawning xterms unnecessarily, which we discussed was a good move.
Covering only 90% of all cases is not enough. We must not break existing setups. That's also why my "Get rid of SUBARCH" series is not upstream. Your second patch changed CONFIG_CON_CHAN to pts, which is ok but not a major issue. The xterms are also not spawning unnecessarily they spawn upon a tty device is opened. With your patch UML create another pts. Thus, the spawning is hidden... I did not push it upstream because it depended on your first one and as I said, it's not critical. This does not mean that I moved it to /dev/null. Again, the plan is to get rid of SUBARCH at all.

make defconfig ARCH=um SUBARCH=x86 (or SUBARCH=i386) will create a defconfig for 32bit. make defconfig ARCH=um SUBARCH=x86_64 one for 64bit.Yes, that's how I prepared the patch in the first place.
So, nothing is broken. If you want "make defconfig ARCH=um" creating a defconfig for the correct arch you need more than your first patch. Again, "Get rid of SUBARCH" series has the same goal. Thanks, //richard
