Subject: [PATCH v2 08/14] powerpc/64s: irq replay remove spurious irq reason
Date: Sat, 12 Aug 2017 02:39:06 +1000 [thread overview]
Message-ID: <20170811163912.28783-9-npiggin@gmail.com> (raw)
In-Reply-To: <20170811163912.28783-1-npiggin@gmail.com>
HVI interrupts have always used 0x500, so remove the dead branch.
