Hi. Sorry for the late reply, but I did not get the message that was archived. I stumbled upon it here: http://osdir.com/ml/centos/2011-05/msg01193.html All I got was this message: I am out of the office until 06/11/2011. I will be out of the office starting 5/27/2011 and will not return until 6/12/2011. I will respond to your message when I return. Note: This is an automated response to your message "CentOS Digest, Vol 76, Issue 28" sent on 5/28/2011 9:00:02 AM. This is the only notification you will receive while this person is away. In response to your question: "Thank you for your suggestion about doing a grep of the source code. We found mmap.S in ../sysdeps/unix/sysv/linux/i386. We looked in mmap.S and found a lot of assembly code. Could you please tell us if any of the assembly code call the kernel syscall handler for mmap.s? Also, we ran make for the kernel Makefile and we obtained the following result shown below. Could you please suggest us how to fix the kernel Makeconfig so that it skips over libc_pic.os? Thank you for your help." May I suggest you join the LKML? http://www.kernel.org/pub/linux/docs/lkml/ I'm sure they are alot more knowledgeable concerning things like tweaking the internals of the Linux kernel.
