From 58834da70ea1dcfb2ee4b41c80350be02ce47d44 Mon Sep 17 00:00:00 2001 From: bde Date: Tue, 16 Jun 1998 14:36:40 +0000 Subject: Use copyout() instead of bcopy() to copy the image to user space. bcopy() caused panics under heavy paging (not quite as suspected - the kernel stack seemed to get corrupted). Fixed long lines.
