Compiling the source RPM file.

I have a rpm for a module  which I extracted like - 
rpm2cpio numactl-2.0.7-3.el6.src.rpm | cpio -idmv 

then I extracted the source like - 
tar -xzvf numactl-2.0.7-3.tar.gz 

then I tried to apply all the patches to available with 
this rpm to the extracted source which results in Hunks and 
rejections.

I want to apply all patches and compile the source and get 
an exe. I am not much aware of the rpm build procedure 

I want to do similar thing to kernel source also 

Please help me...

Arun
