From a895bf8b1e1ea4c032a8fa8a09475a2ce09fe77a Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Sat, 28 Jan 2012 09:09:38 -0300 Subject: edac: move nr_pages to dimm struct MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The number of pages is a dimm property. Move it to the dimm struct. After this change, it is possible to add sysfs nodes for the DIMM's that will properly represent the DIMM stick properties, including its size. A TODO fix here is to properly represent dual-rank/quad-rank DIMMs when the memory controller represents the memory via chip select rows.
