I tried an allmode as suggest by Michael (above). But I get a build error: MODPOST vmlinux.o drivers/android/binder.o: In function `binder_thread_write': binder.c:(.text+0xc750): undefined reference to `__get_user_bad' binder.c:(.text+0xc76c): undefined reference to `__get_user_bad' binder.c:(.text+0xc790): undefined reference to `__get_user_bad' binder.c:(.text+0xc7d4): undefined reference to `__get_user_bad' binder.c:(.text+0xc7f4): undefined reference to `__get_user_bad' So for now I need to do: CONFIG_ANDROID_BINDER_IPC=n How did you get passed this build failure ? > > > > So we could have a 32-bit allmodconfig, but we'd need to chose one of > > the above, and we'd still only be testing some of the code. > > > > Having said that you're the 2nd person to ask about this, so we should > > clearly do something to make a 32-bit allmodconfig easier, even if it's > > not perfect. > > > > cheers
