From d0164c161923ac303bd843e04ebe95cfd03c6e19 Mon Sep 17 00:00:00 2001 From: Sukrit Bhatnagar Date: Thu, 6 Nov 2025 14:28:51 +0900 Subject: [PATCH] KVM: VMX: Fix check for valid GVA on an EPT violation On an EPT violation, bit 7 of the exit qualification is set if the guest linear-address is valid. The derived page fault error code should not be checked for this bit.
