From be9d06bfd48934fbd56ccb7476eabccfa31b4afe Mon Sep 17 00:00:00 2001 From: Glauber Costa Date: Fri, 13 Jun 2008 21:01:46 -0300 Subject: [PATCH] x86: use something common for both architectures. Using explicit hexa (0xFFFFFFUL) introduces an unnecessary difference between i386 and x86_64 because of the size of their long. Use -1UL instead. Signed-off-by: Glauber Costa Signed-off-by: H.
