Subject: [PATCH 9/9] powerpc/64s: POWER8 add missing machine check definitions
Date: Tue, 21 Feb 2017 05:44:30 +1000	[thread overview]
Message-ID: <20170220194430.32602-10-npiggin@gmail.com> (raw)
In-Reply-To: <20170220194430.32602-1-npiggin@gmail.com>

POWER8 uses bit 36 in SRR1 like POWER9 for i-side machine checks,
and contains several similar conditions for link timeouts that
are not currently handled.
