Subject: [PATCH 6/6] powerpc/64s: POWER8 add missing machine check definitions
Date: Tue, 14 Mar 2017 22:36:48 +1000 [thread overview]
Message-ID: <20170314123648.26068-7-npiggin@gmail.com> (raw)
In-Reply-To: <20170314123648.26068-1-npiggin@gmail.com>
POWER8 uses bit 36 in SRR1 like POWER9 for i-side machine checks, and
contains several conditions for link timeouts that are not currently
handled.
