From c637fecb4fe67e2baccef24b9b7e9cb79ee23cf8 Mon Sep 17 00:00:00 2001 From: Atsushi Nemoto Date: Tue, 23 Oct 2007 21:51:19 +0900 Subject: [MIPS] time: Fix cevt-r4k.c for 64-bit kernel The expression "(long)(read_c0_count() - cnt)" can never be a negative value on 64-bit kernel. Cast to "int" before comparison.
