Kernel patches list

[Kapitan]

As Subject, is there a tool
for listing the patches applied
to a kernel? Or something similar?

I have to know what are the patches
in the ubuntu kernels, so i can
recompile my own (i have to test ).

Thanks all.

Or at least is there a .config
that is used for building those
official kernels?

And where can i find it?
