+
+The current RHELSA kernel is using a 42bit VA which is too limiting for
+possible near future workloads.
+Update this to 48 bits. This patch has a dependency on mozjs versions in
+the distro being patched to work with virtual address spaces >47 bits.

The convention for CentOS 7.2 is that any overriding of the default
config's inherited from
Redhat would go into config-centos-sig.  Do we still follow that for
CentOS 7.3?
