Subject: [PATCH] x86/kvm: Remove unused virt to phys translation in kvm_guest_cpu_init()
Date:   Thu, 20 Oct 2022 23:01:13 -0300

Presumably, this was introduced due to a conflict resolution with
commit ef68017eb570 ("x86/kvm: Handle async page faults directly through
do_page_fault()"), given that the last posted version [1] of the blamed
commit was not based on the aforementioned commit.

[1] https://lore.kernel.org/kvm/20200525144125.143875-9-vkuznets@redhat.com/

Fixes: b1d405751cd5 ("KVM: x86: Switch KVM guest to using interrupts for page ready APF delivery")
