Subject: [PATCH v3 03/10] KVM: arm64: selftests: Remove print_reg's dependency on vcpu_config
Date: Fri,  9 Jun 2023 10:12:11 +0800	[thread overview]
Message-ID: <b7faa1f7dd47f6c8e69dcd53fd1213219cc71a04.1686275310.git.haibo1.xu@intel.com> (raw)
In-Reply-To: <cover.1686275310.git.haibo1.xu@intel.com>

From: Andrew Jones <ajones@ventanamicro.com>

print_reg() and its helpers only use the vcpu_config pointer for
config_name(). So just pass the config name in instead, which is used
as a prefix in asserts. print_reg() can now be compiled independently
of config_name().
