From c8923c6b852d3a97c1faad0566e38fca330375a7 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Thu, 13 Oct 2005 14:41:23 -0700 Subject: [NETFILTER]: Fix OOPSes on machines with discontiguous cpu numbering. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Original patch by Harald Welte, with feedback from Herbert Xu and testing by Sébastien Bernard. EBTABLES, ARP tables, and IP/IP6 tables all assume that cpus are numbered linearly. That is not necessarily true. This patch fixes that up by calculating the largest possible cpu number, and allocating enough per-cpu structure space given that. Signed-off-by: David S.
