Subject: [PATCH 0/2] misc: vcpu_stall_detector: Add a PPI interrupt

Hello,


This is a small update of the previously introduced vcpu stall detector
which adds an interrupt to the virtual device to notify the guest VM in
case it stalls. This lets the guest VM to handle the reboot and to
panic in case it expires. 


Thanks,
