[Qemu-devel] [PATCH 2/7] Set PVR in sregs

[Alexander Graf <agraf@suse.de>]

We need to tell the kernel about some initial CPU state we don't have yet,
so let's use the "sregs" IOCTL for that and simply put the Processor Version
Register in there.

Now the kernel knows which guest CPU to virtualize.
