Re: [patch V2 30/67] powerpc/numa: Convert to hotplug state machine

Hi Anna-Maria,

Install the callbacks via the state machine and let the core invoke
the callbacks on the already online CPUs.  

This is causing an oops on ppc64le QEMU, looks like a NULL
pointer:  

Did you tested it against tip WIP.hotplug?

I noticed tip started failing in my CI environment which tests on QEMU.
The failure bisected to commit 425209e0abaf2c6e3a90ce4fedb935c10652bf80

It reproduces running ppc64le QEMU on a x86-64 box. On Ubuntu:

sudo apt-get install qemu-system-ppc gcc-powerpc64le-linux-gnu

make ARCH=powerpc pseries_le_defconfig

make ARCH=powerpc CROSS_COMPILE=powerpc64le-linux-gnu- vmlinux -j4

qemu-system-ppc64 -nographic -vga none -kernel vmlinux
