[Xen-devel] Is is possible to use the latest changeset and old linux kernel?

[Xin Zhao <zhaoxin@xxxxxxxxxxxxxx>]

Hi,

I tried to use the latest changeset of xen-unstable with an old linux 
kernel (2.6.16.33), because some of my codes are developed based on that 
Linux version. It seems that 2.6.18 changes quite a bit interfaces from 
2.6.16.33.
I set the "LINUX_VER    = 2.6.16.33" in the file 
"buildconfigs/mk.linux-2.6-xen". When I did "make world", the xen 
builder did download 2.6.16.33 tarball. But the compiling procedure 
failed with the following error message:
/****************************************************/

So my question is how to use the latest Xen changeset with old Linux 
kernel?
Thanks,
Xin
