[PATCH 1/1] NUMA: Introduce NODE_DATA->node_present_pages(RAM pages)

From: Bernhard Kaindl Some admin tools like 'xl info -n' like to display the total memory for each NUMA node. The Xen backend[1] of hwloc comes to mind too. The total amount of RAM on a NUMA node is not needed by Xen internally: Xen only uses NODE_DATA->node_spanned_pages, bu

[PATCH v4] NUMA: Introduce NODE_DATA->node_present_pages(RAM pages)

From: Bernhard Kaindl At the moment, Xen keeps track of the spans of PFNs of the NUMA nodes. But the PFN span sometimes includes large MMIO holes, so these values might not be an exact representation of the total usable RAM of nodes. Xen does not need it, but the size of the NUMA node's m
