Subject: [PATCH v3 5/7] spapr: move h_home_node_associativity to spapr_numa.c
Date: Thu, 3 Sep 2020 19:06:37 -0300 [thread overview]
Message-ID: <20200903220639.563090-6-danielhb413@gmail.com> (raw)
In-Reply-To: <20200903220639.563090-1-danielhb413@gmail.com>
The implementation of this hypercall will be modified to use
spapr->numa_assoc_arrays input. Moving it to spapr_numa.c makes
make more sense.
