From: "Ken'ichi Ohmichi" 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.
