Subject: [RFC Patch 0/1] Change OOM message from hugetlb to include requested size

This is an attempt to better highlight misconfigured huge pages by showing the
user what was requested verses what was configured.  Moving the messages within
the OOM report will make the configuration or misconfiguration more clear when
an out of memory event occurs.  The previous message has been removed in favour
of this method.
