From 4e8436479ad3be76a3823e6ce466ae464ce71300 Mon Sep 17 00:00:00 2001 From: David Woodhouse Date: Mon, 15 Nov 2021 16:50:21 +0000 Subject: KVM: x86/xen: Fix get_attr of KVM_XEN_ATTR_TYPE_SHARED_INFO In commit 319afe68567b ("KVM: xen: do not use struct gfn_to_hva_cache") we stopped storing this in-kernel as a GPA, and started storing it as a GFN. Which means we probably should have stopped calling gpa_to_gfn() on it when userspace asks for it back.
