Subject: [PATCH 1/2] dlpar.c: introduce dlpar_unisolate_drc()
Date: Fri, 16 Apr 2021 18:02:15 -0300 [thread overview]
Message-ID: <20210416210216.380291-2-danielhb413@gmail.com> (raw)
In-Reply-To: <20210416210216.380291-1-danielhb413@gmail.com>
Next patch will execute a set-indicator call in hotplug-cpu.c.
Create a dlpar_unisolate_drc() helper to avoid spreading more
rtas_set_indicator() calls outside of dlpar.c.
