Dear Harishkumar;
I already know how to find the changes, please see my 1st e-mail below.

hundreds of files are added or modified.

Sure about this? Check the output of `file vmlinux`

Hi
Memcpy is both- a system call as well as a user library function.
Implementation differs

memcpy is *not* a system call. It is a standard C library function.
System calls are those where you enter the kernel mode and ask your OS to do
something for you (like read/write from disk).
For memory copy you don't need to take the service

Thanks,

Hello guys,
As I have recently came to know about QEMU which is a quick emulator and
support emulation of ARM architecture.
I wanted to boot linux onto QEMU, by setting up various nodes and devices
from scratch. I want everything to be hand coded or atleast should have an
idea of the (what my
I modified my module (m.c). Still sending buffer from user space using
ioctl, but instead of copying data from buffer provided by user, I have
allocated (kmalloc) a buffer and I copy from this buffer to another kernel
buffer which is allocated each time this module ioclt is invoked.
hello,I want to be added to this mailing list.
