From 198bd06bbfde2984027e91f64c55eb19a7034a27 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Tue, 5 Apr 2011 00:23:59 +0200 Subject: [PATCH] x86-32, numa: Remove redundant node_remap_size[] Remap area size can be determined from node_remap_start_vaddr[] and node_remap_end_vaddr[] making node_remap_size[] redundant. Remove it. While at it, make resume_map_numa_kva() use @nr_pages for number of pages instead of @size.
