Subject: [PATCH] arm: Fix arch_initialise_vcpu to be unsupported
Date: Tue,  6 Jul 2021 12:28:53 +0200	[thread overview]
Message-ID: <20210706102853.10251-1-michal.orzel@arm.com> (raw)

Function arch_initialise_vcpu is not reachable as the
VCPUOP_initialise is an unsupported operation on arm.
Modify the function by adding ASSERT_UNREACHABLE() and
returning -EOPNOTSUPP.
