Subject: Common config for N900 and D4

Hi!

Aaro, I know I have asked before, but if you have common config for
N900 and Droid4, please send me a copy. Yes, it should be somewhere in
my inbox already, but I can't find it and version for v4.17 would be
more useful.

While trying to came up with common config, I hit:

Which sounds like kernel bug. I was running Droid 4 in !CONFIG_SMP
configuration by mistake, maybe that has something to do with it. I'll
try to investigate more.

Best regards
