Subject: [PATCH 08/13] powerpc/64s: irq replay remove spurious irq reason
Date: Sun,  6 Aug 2017 03:02:36 +1000	[thread overview]
Message-ID: <20170805170241.22966-9-npiggin@gmail.com> (raw)
In-Reply-To: <20170805170241.22966-1-npiggin@gmail.com>

HVI interrupts have always used 0x500, so remove the dead branch.
