Correct EXTRAVERSION in kernel Makefile

Correct EXTRAVERSION in kernel Makefile

[Niraj Tolia]

Would it be possible to have the correct EXTRAVERSION value (-xen0 and
-xenU) in the Makefiles for the different kernels that are built by
Xen? Makefiles for drivers that are not in the kernel tree often try
to grok 'linux-src/Makefile' to learn what version of kernel was
compiled.

I personally hit the problem when trying to compile the Cisco iSCSI
driver for Xen.

Thanks,
Niraj

EXTARVAERSION is overridden by the arch/xen/Makefile using the same
technique useed by UML and various other architectures.

I can't recall having to do anything special to build the Cisco
iSCSI initiator.

The Makefile for the Cisco iSCSI initiator (3.4.3) uses awk and sed to
extract EXTRAVERSION from the Makefile. It then spits out warnings on
screen as 'uname -r' does not match what it gets from the Makefile.

On close inspection, it turns out that the warnings are just noise and
things will work if you are careful. So I guess we are ok for now.
