Subject: [PATCH 7/8] KVM: arm64: Drop legacy copro shadow register
Date: Mon,  2 Nov 2020 19:16:08 +0000	[thread overview]
Message-ID: <20201102191609.265711-8-maz@kernel.org> (raw)
In-Reply-To: <20201102191609.265711-1-maz@kernel.org>

Finally remove one of the biggest 32bit legacy: the copro shadow
mapping. We won't missit.
