Subject: [PATCH v2 1/7] x86/mce: Rename "first" function as "early"
Date: Fri, 14 Feb 2020 14:27:14 -0800	[thread overview]
Message-ID: <20200214222720.13168-2-tony.luck@intel.com> (raw)
In-Reply-To: <20200214222720.13168-1-tony.luck@intel.com>

It isn't going to be first on the notifier chain when we move
the CEC code to be a normal user of the notifier chain.

Fix the enum for the MCE_PRIO symbols to list them in reverse
order so that the compiler can give them numbers from low to
high priority. Add an entry for MCE_PRIO_CEC as the highest
priority.
