Subject: [PATCH] Mention Intel Atom in Kconfig.cpu (less garbled this time)

[Appoligies for the garbled first attempt at posting this.  Blame the
original author for the long lines!?]

Am I right in thinking that CONFIG_MCORE2 is the correct choice for an 
Intel Atom?  (It seems to work for me, so far.)  If this is true, since 
there are quite a lot of these chips in circulation now and the choice 
is not obvious, I think it would be helpful to add something along the 
following lines to arch/x86/Kconfig.cpu.
