[PATCH v2 16/36] KVM: nVMX: Enable guest deadline and its shadow VMCS field
Posted by isaku.yamahata@intel.com 3 weeks, 6 days ago 
From: Isaku Yamahata <isaku.yamahata@intel.com>

Support the guest deadline and the guest deadline shadow VMCS field.

Signed-off-by: Isaku Yamahata <isaku.yamahata@intel.com>
---
Changes:
v1 -> v2:
- the offsets of vmcs fields changed due to rebase.
