+Subject: [PATCH 16/93] KVM: nVMX: Update vmcs12->guest_linear_address on
+ nested VM-exit
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+[ Upstream commit d281e13b0bfe745a21061a194e386a949784393f ]
+
+The guest-linear address field is set for VM exits due to attempts to
+execute LMSW with a memory operand and VM exits due to attempts to
+execute INS or OUTS for which the relevant segment is usable,
+regardless of whether or not EPT is in use.
+
+Fixes: 119a9c01a5922 ("KVM: nVMX: pass valid guest linear-address to the L1")
