Subject: [PATCH 25/56] KVM: arm64: Compile remaining hyp/ files for both VHE/nVHE
Date: Wed, 5 Aug 2020 18:56:29 +0100 [thread overview]
Message-ID: <20200805175700.62775-26-maz@kernel.org> (raw)
In-Reply-To: <20200805175700.62775-1-maz@kernel.org>
From: David Brazdil <dbrazdil@google.com>
The following files in hyp/ contain only code shared by VHE/nVHE:
vgic-v3-sr.c, aarch32.c, vgic-v2-cpuif-proxy.c, entry.S, fpsimd.S
Compile them under both configurations. Deletions in image-vars.h reflect
eliminated dependencies of nVHE code on the rest of the kernel.
