Subject: [PATCH 39/59] KVM: arm64: nv: Move last_vcpu_ran to be per s2 mmu
Date: Fri, 21 Jun 2019 10:38:23 +0100
Message-ID: <20190621093843.220980-40-marc.zyngier@arm.com> (raw)
In-Reply-To: <20190621093843.220980-1-marc.zyngier@arm.com>

last_vcpu_ran has to be per s2 mmu now that we can have multiple S2
per VM. Let's take this opportunity to perform some cleanup.
