[elrepo] kernel-ml compilation flags

Hello,

I have installed kernel-ml on two machines, both being NUMA machines.

On the first machine (a vm running with emulated nodes through qemu),
the CONFIG_NUMA_BALANCING flag was used for configuring the kernel.
On the second, a "real" NUMA machine, that flag was not set.

Why did this happen? Other NUMA-related flags were set on the second
machine, which I believe means that the kernel detected it is dealing
with a NUMA machine.

Maybe a more important question is: is it possible to define which flags
to use when installing the kernel? I'd rather not go through a manual
compilation of the kernel.

Thanks,
Martin
