Subject: [PATCH v7 12/15] machine: Move smp_prefer_sockets to struct SMPCompatProps
Date: Mon, 23 Aug 2021 20:28:01 +0800	[thread overview]
Message-ID: <20210823122804.7692-13-wangyanan55@huawei.com> (raw)
In-Reply-To: <20210823122804.7692-1-wangyanan55@huawei.com>

Now we have a common structure SMPCompatProps used to store information
about SMP compatibility stuff, so we can also move smp_prefer_sockets
there for cleaner code.

No functional change intended.
