[uml-user] PB Compiling the kernel - `smp_num_cpus' undeclared

[Anil K. R <an...@cd...>]

Hi all,
I just downloaded 
	linux-2.4.10.tar.bz2 and uml-patch-2.4.10-1.bz2
created /usr/src/uml untarred the linux kernel and patched it with uml using 
the command

cat uml-patch-2.4.0-prerelease.bz2 | bunzip2 - | patch -p1
as per directions on the home page of user_mode_linux
I also did
	make xconfig ARCH=um 
	make dep ARCH=um
now the problem is when I give the command
	make linux ARCH=um
I get the following error

In file included from ksyms.c:17:
/usr/src/uml/linux/include/linux/kernel_stat.h: In function `kstat_irqs':
/usr/src/uml/linux/include/linux/kernel_stat.h:48: `smp_num_cpus' undeclared 
(first use in this function)
/usr/src/uml/linux/include/linux/kernel_stat.h:48: (Each undeclared 
identifier is reported only once
/usr/src/uml/linux/include/linux/kernel_stat.h:48: for each function 
it appears
in.)
make[2]: *** [ksyms.o] Error 1

make[1]: *** [first_rule] Error 2
make[1]: Leaving directory `/usr/src/uml/linux/kernel'
make: *** [_dir_kernel] Error 2

can somebody please guide me out of this. This is the first time I am trying 
to compile the kernel.

Thankyou
