I also noticed from the config you mentioned in this thread and the
one which I have with me (with which all things compiled)
there are following differences

# CONFIG_XEN_DEBUG_FS is not set
CONFIG_XEN_BLKBACK_PAGEMAP <--- is completely missing
# CONFIG_XEN_GNTDEV is not set

Is there a way to undo things specially for the make commands?
Here I see this related files in

/mnt/1/fajar/linux-2.6-xen <-- basically here is where I did all
compile on this pv-ops dom0 kernel.

I did a find on xen-4.0.1
and found only at one place where every thing was untarred (so if I
delete this and do make xen etc again will that be Ok)
