ms/kvm/x86: add a hv_stimer pending to the list of vcpu's awaking events
In RHEL 7.3 the infrastructure code responsible for checking the vcpu
runnable state has been reworked. RHEL 7.3 doesn't support hyper-v stimers,
thus the hv_stimer pending check didn't appear in the reworked code.
The hv_timer pending check hasn't been ported while moving from 7.2 to 7.3
kernel. This has led to hanging on of windows guests on during OS
installation
and OS shutting down.
The patch fixes that by adding a missing piece of code to the vcpu runnable
check, to be merged into afa32dc ("ms/kvm/x86: Hyper-V SynIC timers").
