This patchset adds ppc64 server side support for software breakpoint
and extends the use of illegal instruction as software
breakpoint across ppc platform.

Patch 1, adds kernel side support for software breakpoint.
Design is that, by using an illegal instruction, we trap to
hypervisor via Emulation Assistance interrupt, where we check
for the illegal instruction and accordingly we return to Host
or Guest. Patch also adds support for software breakpoint
in PR KVM.

Patch 2,extends the use of illegal instruction as software
breakpoint instruction across the ppc platform. Patch extends
booke program interrupt code to support software breakpoint.

Thanks, applied to kvm-ppc-queue.
