[PATCH 0/2] KVM: x86: Correct use of kvm_rip_read()
From: Adrian Hunter
Date: Tue Apr 15 2025 - 06:54:20 EST
Hi
Here are a couple of tweaks to dodge kvm_rip_read() in tracepoints and
KVM_PROFILING when guest_state_protected.
This avoids, for example, hitting WARN_ON_ONCE in vt_cache_reg() for
TDX VMs.

KVM: x86: Do not use kvm_rip_read() unconditionally in KVM tracepoints
KVM: x86: Do not use kvm_rip_read() unconditionally for KVM_PROFILING
