Hi Alexander,

After merging the kvm-ppc tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

I have used the version of the kvm-ppc tree from next-20120703 for toda=

Ah, yes, thanks. I kept the old, broken version in my tree to make sure I=

 have the dependencies for (and

don't forget) the (hopefully good) patches that follow on top, but was pl=

anning to replace it once we

have a new version of the CURRENT_THREAD_INFO one.

Stuart, could you please send a new version of the CURRENT_THREAD_INFO pa=

tch?

Yes, will send that shortly.
