Subject: [PATCH v4 13/15] arm64: kvm: Compile remaining hyp/ files for both VHE/nVHE
Date: Thu, 25 Jun 2020 14:14:18 +0100 [thread overview]
Message-ID: <20200625131420.71444-14-dbrazdil@google.com> (raw)
In-Reply-To: <20200625131420.71444-1-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.
Signed-off-by: David Brazdil <dbrazdil@google.com>
