From 56d6d1a73d9e5ddd9eb1a7baeeda30803ba44879 Mon Sep 17 00:00:00 2001 From: Manish Ahuja Date: Tue, 10 Jul 2007 05:03:45 +1000 Subject: [POWERPC] Fix loop with unsigned long counter variable This fixes a possible infinite loop when the unsigned long counter "i" is used in lmb_add_region() in the following for loop: for (i = rgn->cnt-1; i >= 0; i--) by making the loop counter "i" be signed.
