From 2c4fd91d26643504011b7c2b75563a437e19d6a1 Mon Sep 17 00:00:00 2001 From: Sean Christopherson Date: Mon, 3 Dec 2018 13:53:03 -0800 Subject: [PATCH] KVM: VMX: Expose various module param vars via capabilities.h Expose the variables associated with various module params that are needed by the nested VMX code. There is no ulterior logic for what variables are/aren't exposed, this is purely "what's needed by the nested code". Note that @nested is intentionally not exposed.
