Xen devel - May 2013 - Compiling 2.6.18-xen Dom0 Error: error: ‘coretemp_cpu_notifier’ undeclared

Hi,

Can anyone help me to solve this problem that I have while compiling the
2.6.18.8 Dom0 kernel?
My environment is Xen-4.2.2 + CentOS6.3 32bit + 2.6.18.8 Dom0. The details
is as the following.

# make install-kernels
...
  CC [M]  drivers/hwmon/coretemp.o
/root/Xen/xen-4.2.2/linux-2.6.18-xen.hg/drivers/hwmon/coretemp.c: In
function ‘coretemp_init’:
/root/Xen/xen-4.2.2/linux-2.6.18-xen.hg/drivers/hwmon/coretemp.c:523:
error: ‘coretemp_cpu_notifier’ undeclared (first use in this function)
/root/Xen/xen-4.2.2/linux-2.6.18-xen.hg/drivers/hwmon/coretemp.c:523:

/root/Xen/xen-4.2.2/linux-2.6.18-xen.hg/drivers/hwmon/coretemp.c: In
function ‘coretemp_exit’:
/root/Xen/xen-4.2.2/linux-2.6.18-xen.hg/drivers/hwmon/coretemp.c:545:
error: ‘coretemp_cpu_notifier’ undeclared (first use in this function)
make[7]: *** [drivers/hwmon/coretemp.o] Error 1
make[6]: *** [drivers/hwmon] Error 2
make[6]: *** Waiting for unfinished jobs....
...

Any suggestion is appreciated.

For one, this sort of problem normally isn't that difficult to sort
out, so being on xen-devel we expect you to invest a little bit
of effort here yourself.

And then I'm not seeing similar build problems, and looking at the
code both producer and consumers of the symbol in question are
sitting in #ifdef CONFIG_HOTPLUG_CPU blocks, so I can't really
see how (without you having modified the code) the consumers
would get compiled without the producer also getting compiled.
