Subject: [PATCH v3 10/17] KVM: arm64: debug: Drop useless vpcu parameter
Date: Mon, 6 Jul 2020 13:54:18 +0100 [thread overview]
Message-ID: <20200706125425.1671020-11-maz@kernel.org> (raw)
In-Reply-To: <20200706125425.1671020-1-maz@kernel.org>
As part of the ongoing spring cleanup, remove the now useless
vcpu parameter that is passed around (host and guest contexts
give us everything we need).
