Subject: [PATCH 8/8] KVM: arm64: Drop kvm_coproc.h
Date: Mon,  2 Nov 2020 19:16:09 +0000	[thread overview]
Message-ID: <20201102191609.265711-9-maz@kernel.org> (raw)
In-Reply-To: <20201102191609.265711-1-maz@kernel.org>

kvm_coproc.h used to serve as a compatibility layer for the files
shared between the 32 and 64 bit ports.

Another one bites the dust...
