Subject: [PATCH v3 2/8] cpus: Move do_run_on_cpu into softmmu/cpus.c
Date: Wed, 28 Jul 2021 14:31:45 -0400	[thread overview]
Message-ID: <20210728183151.195139-3-peterx@redhat.com> (raw)
In-Reply-To: <20210728183151.195139-1-peterx@redhat.com>

It's only used by softmmu binaries not linux-user ones.  Make it static and
drop the definition in the header too.

Since at it, initialize variable "wi" with less loc.
