Subject: [PATCH 20/20] spapr: Eliminate SpaprIrq::init hook
Date: Wed, 25 Sep 2019 16:45:34 +1000	[thread overview]
Message-ID: <20190925064534.19155-21-david@gibson.dropbear.id.au> (raw)
In-Reply-To: <20190925064534.19155-1-david@gibson.dropbear.id.au>

This method is used to set up the interrupt backends for the current
configuration.  However, this means some confusing redirection between
the "dual" mode init and the init hooks for xics only and xive only modes.

Since we now have simple flags indicating whether XICS and/or XIVE are
supported, it's easier to just open code each initialization directly in
spapr_irq_init().  This will also make some future cleanups simpler.
