From 4481374ce88ba8f460c8b89f2572027bd27057d0 Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Mon, 21 Sep 2009 17:03:05 -0700 Subject: mm: replace various uses of num_physpages by totalram_pages Sizing of memory allocations shouldn't depend on the number of physical pages found in a system, as that generally includes (perhaps a huge amount of) non-RAM pages. The amount of what actually is usable as storage should instead be used as a basis here. Some of the calculations (i.e. those not intending to use high memory) should likely even use (totalram_pages - totalhigh_pages).
