The patch titled
vmcoreinfo: add page flags values
has been removed from the -mm tree. Its filename was
vmcoreinfo-add-page-flags-values.patch
This patch was dropped because it was merged into mainline or a subsystem tree

Subject: vmcoreinfo: add page flags values
From: "Ken'ichi Ohmichi" <oomichi@xxxxxxxxxxxxxxxxx>
Add some values of page flags to the vmcoreinfo data.
The vmcoreinfo data has the minimum debugging information only for dump
filtering. makedumpfile (dump filtering command) gets it to distinguish
unnecessary pages, and makedumpfile creates a small dumpfile.
An old makedumpfile (v1.2.4 or before) had assumed some values of page flags
internally, and this implementation could not follow the change of these
values. For example, Christoph Lameter is changing these values by the
follwing patch: http://lkml.org/lkml/2008/2/29/463
So a new makedumpfile (v1.2.5) came to need these values and I created this
patch to let the kernel output them.
