From 07da1ffaa1373f99331712faa67a00b5b807dfe8 Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Fri, 5 Jun 2020 14:08:13 +0100 Subject: KVM: arm64: Remove host_cpu_context member from vcpu structure For very long, we have kept this pointer back to the per-cpu host state, despite having working per-cpu accessors at EL2 for some time now. Recent investigations have shown that this pointer is easy to abuse in preemptible context, which is a sure sign that it would better be gone. Not to mention that a per-cpu pointer is faster to access at all times.
