KVM: PPC: Book3S HV: Enable hypervisor virtualization interrupts while in guest
The new XIVE interrupt controller on POWER9 can direct external interrupts to the hypervisor or the guest. The interrupts directed to the hypervisor are controlled by an LPCR bit called LPCR_HVICE, and come in as a "hypervisor virtualization interrupt". This sets the LPCR bit so that hypervisor virtualization interrupts can occur while we are in the guest. We then also need to cope with exiting the guest because of a hypervisor virtualization interrupt. Signed-off-by: Paul Mackerras <paulus@ozlabs.org>
