Subject: [PATCH v4 07/15] hw/i386/pc: Pass the CPUArchIdList array by argument
Date: Mon, 19 Aug 2019 00:54:06 +0200
Message-ID: <20190818225414.22590-8-philmd@redhat.com> (raw)
In-Reply-To: <20190818225414.22590-1-philmd@redhat.com>

Pass the CPUArchIdList array by argument, this will
allow us to remove the PCMachineState argument later.

Suggested-by: Samuel Ortiz <sameo@linux.intel.com>
