My system is just qemu booted with:

-smp 8 -m 8192 -numa node,nodeid=0,cpus=0-3 -numa node,nodeid=1,cpus=4-7

Watch the "PERCPU:" line early in boot, and you can see the "Embedded"
come and go with or without your patch:

[    0.000000] PERCPU: Embedded 11 pages/cpu @f3000000 s30592 r0 d14464
vs
[    0.000000] PERCPU: 11 4K pages/cpu @f83fe000 s30592 r0 d14464

I don't have a fix handy because I'm working on the original problem,
but I just happened to run across this during a bisect.

Just tested 3.7-rc7 w/ qemu and it works as expected here.

Can you please boot with the following debug patch and report the boot
message before and after?

Hi Tejun,

I just tested with 3.7-rc7 and I'm seeing the expected behavior now.
Looks like it got fixed along the way somewhere.  I was bisecting way
back in the 2.6.3x's.  Sorry of the noise.
