Tested this functionality using SEA support.
++Stephen,
Something to be aware of, this patch will conflict with https://lkml.org/lkml/2017/9/14/663
It may make sense to just remove the conditions for the NMI configs as part of this patch or in a series with this patch to avoid merge conflicts.
In your patch, you only remove ACPI_APEI_SEA for the ARCH_HAVE_NMI_SAFE_CMPXCHG, do you need to remove it for the HAVE_NMI?
From the latest comments it sounds like Stephen was going to remove it
from both.
