Re: [kbuild-all] [PATCH 5/6] KVM: PPC: Book3S HV: Send IPI to host core to wake VCPU

["Suresh E. Warrier" <warrier@linux.vnet.ibm.com>]

Hi Fengguang,

I understand the problem.

I will send you the URL for the powerpc git tree once my patches
are pulled in so that we can then pass that to the robot.

Thanks.
