[Xen-users] Patching the kernel

[Jaume Sabater <jsabater@xxxxxxxxxxxxx>]

Hello everyone.

I am working on Debian Sid AMD64. I downloaded and uncompressed the 
unstable version of Xen, took the patches inside 
xen-unstable/patches/linux-2.6.16.29 and tried to apply all of them to a 
pristine Linux kernel 2.6.16.29. Two problems I found:
1. The patch "x86-elfnote-as-preprocessor-macro.patch" produced this error:

The text leading up to this was:
--------------------------
|diff -pruN ../orig-linux-2.6.16.29/include/linux/elfnote.h 
./include/linux/elfnote.h
|--- ../orig-linux-2.6.16.29/include/linux/elfnote.h    2006-09-19 
14:06:10.000000000 +0100
|+++ ./include/linux/elfnote.h  2006-09-19 14:06:20.000000000 +0100
--------------------------
File to patch:


So, I skipped the patch. Then I tried to "make menuconfig" in the 
kernel, but I could not find the expected option "Enable Xen compatible 
kernel" under "Processor type and features". The "Xen" group of options 
was not present either.
What I am trying to do is to test the upcoming new stable release on a 
pristine kernel on my Debian, with my custom configuration (I don't use 
any modules in the kernel, for instance). I want to compile the kernel 
using the Debian's kernel-package tools thus producing a .deb package.
Could someone please tell me what I am missing or point me to some docs 
or scripts where I could find out the right way to patch the kernel?
Thanks in advance.

P.S. So far, I compiled xen-unstable (I let the scripts do their work). 
Once it ended, I used the linux-2.6.16.29-xen directory that was created 
and copied my .config there. Then make-kpkg clean && make-kpkg 
kernel-image and I got what I wanted, but I'd really like to know how it 
works.
