[ 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.
