Subject: [Qemu-devel] [PATCH qemu v5 07/18] memory: Cleanup after switching to FlatView
Date: Thu, 21 Sep 2017 18:50:59 +1000 [thread overview]
Message-ID: <20170921085110.25598-8-aik@ozlabs.ru> (raw)
In-Reply-To: <20170921085110.25598-1-aik@ozlabs.ru>
We store AddressSpaceDispatch* in FlatView anyway so there is no need
to carry it from mem_add() to register_subpage/register_multipage.
This should cause no behavioural change.
